The first thing that went wrong was the check engine light coming on... now every so often it flickers on and off or sometimes even blinks on and off...... at the same time the RPMs drop low like it wants to stall out but it doesn't only once in awhile (it's only stalled out on me like 3 times). The lights flicker on the instrument panel and the radio. i took it to autozone and they plugged it in to something and told me it was a cylinder 1 misfire i changed the spark plugs and they told me that it doesn't have wires. i also changed the oil and put injector cleaner. I think auto zone is trying to mess up my car because they couldn't even tell me what kind of oil it took and then tried to talk me into buying it anyway i didn't until i knew for sure what kind but still i need help to know what is wrong

Welcome Aboard, I see this is your first post:

:welcomesmiley:

I changed the heading on your thread to be more descriptive, the PLEASE someone help!!!!, you had, scares me! LOL...

The flickering check engine light is typically the sign of a misfire.

Something is causing you to misfire. Autozone plugged in a DTC Code reader and they were able to determine that your #1 cylinder is misfiring.

The PCM has determined that your #1 cylinder is not carrying its load due to it not firing the fuel mixture charge. This can be caused by mechanical problems affecting compression (valve leaking for various reasons, CAM lobe damage, push rod, etc), an ignition problem (spark plug, ignition wire, coil, cap if equipped), or fuel problems (fuel injector, vacuum leak, etc).

Go to this page and under the TUNE-UP heading you will find some good MISFIRE articles. If you are lucky you probably just need a tune up.

Pay no attention to Autozone, they are good stores to get parts and supplies from but they are usually staffed by yutes who think they know more than they do as they deal with it all day. They typically meet people who are clueless about mechanics/auto repair/auto knowledge and that magnifies their sense that they are knowledgeable. Truthfully their knowledge for the most part is limited to looking up application specific replacement aftermarket parts.

I used to get upset when I went to these places because they assume that you are not knowledgeable and I felt the need to assert my knowledge. As I have gotten older, I realize that is a waste of energy. Its the, "if you wrestle with pigs are you going to get dirty scenario". Since I buy my parts on line, I rarely have to deal with it.

That said, if you are armed with information you immediately gain respect with the parts counter and your mechanic. If I walk through the doors and say, "I need the PRE-CAT O2 Sensor, it has a FEMALE connector on it, what do you have BOSCH?", they are on the back of their heels from the outset.

We can help you to be ARMED with information, OR, we can help you to diagnose and fix this problem if you want. Already you know that you might need a tune up, you are missing on your #1 cylinder, and it can be caused by a bunch of issues.

What do you plan to do fix it yourself or take it in to a mechanic? Which ever way you decide to go, we can help you to proceed

I don't know your car first hand, but if they said you don't have ignition wires, in 2000 you probably have COP ignition (coil on plug). You have coil banks on the 2000 and probably need to replace a coil bank. But that is preliminary.

Tell us more

V6 Engine? Lift hood and look for markings for Liters on white tags and on the engine

How many miles

Has it ever been tuned up?

Now when I drive omg its scarey.... The sport mode light flashes and it feels like it does shift but according to the rpms it does shift but when accelerating from stop i have to push the gas alot and it still feels like we are hardly moving............ Auto Zone says problem A is causing problem B..... Problem A cylinder 1 Misfire, problem B Transaxle switch the funny thing the guy wrote down like 3 or 4 codes but tells me there is only 1 problem i need to fix so the whole car is fixed..... I love my caddy but I definetly wish i could fix it so i could LOVE to drive right now i hate moving it and the weather is about to get nice!!!!!!! i am getting ready to change one of the coil banks on the car.... hopefully it fixes it!

I fixed the cylinder one misfiring just by changing the coil!!!! now I just have to come up with more money so i can fix the transaxle range switch. This car has cost me nothing but a fortune to fix and i am almost ready to just get rid of it. It seems like once one thing goes wrong everything goes wrong. Hopefully i can come up with the $250 to fix it otherwise i have wasted: $4700 for the car, $85 for the coil, $50 for spark plugs, $50 for the oil change, not to mention when i got this car it doubled my insurance.

OF course, we told you it was probably the COIL pack above.

Listen, I hear your frustration, but please LOSE IT.. You are driving a 9 year old car, you know nothing about the history and its GOING TO NEED REPAIRS PERIOD!!! Wipe your nose

Here are your alternatives, BUY A NEW CAR, PAY A PAYMENT, HAVE A WARRANTY, HAVE NO REPAIR COSTS!

OR

Buy a USED CAR, DONT PAY A PAYMENT, DONT HAVE A WARRANTY, and PAY REPAIR COSTS

Now IF you need to take your car for repairs, its going to be expensive, that is why many of us are Do It Yourselfers!

If you are NOT mechanically inclined ANY used car can be expensive to own, BUT NEW CAR PAYMENTS CAN BE EXPENSIVE for the quality of car you are driving

THERE IS NO FREE LUNCH!!!!!

Once the repairs on a USED CAR surpass the cost of a NEW car on a monthly basis, its time to get rid of the USED car...

I don't think that you understand my frustration. I am a college student, when i bought this car it took all my money not most of it not some of it ALL of it. I had to have a car to get to school and after only having the car for 3 weeks all these problems come up. When i bought the car i asked the guy WHAT IS WRONG WITH IT, he says nothing, i knew i didn't have money to fix it. This all goes back to I GOT SCREWED by the dealer. Its not like i just went anywhere I bought the car from the dealership off of the used lot it would have been nice of him to say BOTH coil banks are cracked, and you might need to put some work into the car and then i would have bought a different car. Its disappointing all i wanted was a dependable car to get me to and from school and to and from work all i got was a smurfed up car and now i am BROKE it took all my taxes to fix one problem and i did it myself. I am not incompetent with cars i can do a lot on my own and if i could afford to pay for the part it would be fixed in no time. According to Auto zone and other auto part stores they cant order it it has to come from the dealer so now i have to pay $250 for another part BS makes me mad not to mention school and work. Is there anywhere i could find this part for cheaper than that????

I can kinda understand your feelings but....

Your first mistake was, you believed a USED CAR SALESMAN who works on commission.

Your second mistake was you spent ALL OF YOUR MONEY on a 9 year old car and didn't keep anything in reserve for possible trouble.

Your third mistake was you didn't check insurance rates BEFORE you bought the car.

It is also very possible that the salesman did not know about the coil packs.

You said you drove it three weeks before any problems.

If it was running great when you bought it, (and I ASSUME it was or you wouldn't have bought it in the first place)...how was he to know that you would have trouble three weeks later?

Now a question for you...did you go back to the dealer and ask for help to remedy any of the problems you are having, since you had only had it for three weeks?

Be polite and ask for help.

Remind them that they told you that NOTHING was wrong with the car.

They may or may not help you out, but it sure don't hurt to ask. :D

Most NINE YEAR OLD VEHICLES will have an occasional problem.

That is just a fact of life that you will learn if you keep and drive older cars.

You have to keep a little reserve fund in place to take care of the problems when they happen and you didn't do that.

You say that you can do a lot of things yourself, but it appears that you paid $50 bucks for an oil change.

You could have done that YOURSELF and for probably less than $20 bucks.

You paid another $50 bucks for a plug change.

Why didn't you change the plugs yourself?

It would have been a LOT LESS than $50 bucks.

Have you checked around at wrecking yards or at some of the online parts sources for the other part you need to see if you can get it cheaper?

There is ALWAYS more than one way to do something.

Ease up on the crying and complaining (it accomplishes nothing) and we will try and help you get the car in good shape as economically as possible.

The Spark plugs cost $7.50 each maybe a little more there are 6 of them you do the math i am not stupid the guy at auto zone said those are the ones u have to have or your car will melt through them in less than a month. The oil change: Pennzoil for higher mileage cars not bullshit oil good oil plus a filter not a cheap filter i paid like 15 bucks for it and my car takes 6 quarts of oil not 5, The coil cost 79.99 at the auto parts store plus tax. The Dealer won't help me because according to him it's not his problem. not only were both coils cracked the car doesn't even shift right almost undrivable and yeah i should have saved money in case but the reality is i didn't and how hard is it at the dealership for them to look at the codes the machine reads is really quite simple.

enough venting i have checked some salvage yards and they said my car is too new and not many people junk cars like that.... so what online auto sources do you suggest? I have never bought online parts before...... Another question i have never changed a Transaxle Range switch is it hard? I know where its located

I just checked that site i didn't see the part in that list, at the Dealership they told me the part is called a Transaxle Range switch, is that a fancy name, could it be called something else???? I wish i would have known about that site before the coils were a lot cheaper on there, when i replace the other one i will definitely buy it there!

Kelly,

I apologize got the criticism about the oil and plugs.

I didn't realize exactly what you had bought.

Can you clear all the codes on your car and then see what codes come back and then post them on here?

That would really help us with diagnosing the problem and helping you get it fixed.

Listen, one thing you are going to learn in life, is that God helps those who help themselves.

Chose some of the YARDS in your immediate area, and start making calls and ASK FOR THE PART!

I WASTED 30 valuable minutes searching it myself but THAT PART can be anywhere, electronics, transaxle, communications, etc

AT LEAST YOU KNOW THAT THERE ARE 2000 CATERA'S IN THE JUNK YARD AND THE GUY THAT MADE THAT STATEMENT THAT IT IS TOO NEW IS AN *smurf* HOLE, START MAKING CALLS, YOU WILL GET ONE

how would you clear the codes if you tell me how i can do it i have never had to do it but if u tell me how i dont see y not........ the only code i have now is P0705 or P705... I am also thinking this could be a computer problem because when i start the car sometimes the sunroof will open by its self even when it is on close and it seems to be hard to get it to close back.

P0705 - Trans Range Switch Circuit

Check the sunroof switch to see if it is shorted to open the sun roof, it is not likely that the sun roof is wired into the PCM

Your Transmission Control Module is NOT necessarily bad. As a matter of fact, it is probably doing its job just fine by sending this code to the ECM.

Here is what the manual says for this particular code:

DTC P1700 Transmission Control Module (TCM) Requested MIL Illumination

Circuit Description

This DTC indicates that a transmission related OBD II failure has occurred. The Transmission Control Module (TCM) controls a dedicated Service Transmission Lamp (STL) which illuminates when a fail reports by certain non-emissions related TCM diagnostics. The TCM has no direct control of the engine MIL, but if a transmission fault occurs that is emissions related, the engine MIL must illuminate. A MIL Request circuit between the ECM and the TCM provides a means for illuminating the MIL, even though the fault was detected by the TCM. This circuit is pulled up to B+ within the ECM. In order to illuminate the MIL, the TCM pulls the circuit low. The ECM detects this and DTC P1700 is set, which illuminates the MIL.

Conditions for Running the DTC

Tested continuously

Conditions for Setting the DTC

An OBD II transmission DTC has been stored by the TCM.

Action Taken When the DTC Sets

The ECM illuminates the Malfunction Indicator Lamp (MIL) 1 second after the request from the TCM is received.

The ECM records operating conditions at the time the TCM initiates the request. This information will store in the Freeze Frame.

Conditions for Clearing the MIL/DTC

The ECM will turn the MIL off approximately 1 second after the TCM request is no longer received.

A History DTC clears after forty consecutive warm-up cycles if no failures report by this diagnostic or any other emission related diagnostic.

The ECM battery voltage is interrupted.

The scan tool clears the MIL/DTC.

DTC P1700 - MIL Requested By TCM
