Dual overhead cam timing
Peptember posted a topic in Cadillac Electronic Modifications, Upgrades, and Additions
to keep your dual overhead cams in place in relation to each other while you do a head job just set your timing at the beginning of its cycle then take two crescent wrenches and put them on the hexes at the end of your camshafts so that they are faced in word and cross each other this is where you can take a vice grip and lock them together to keep them from moving so that you are able 2 put your head back into place saving you time - Today

Nah, you will be fine. We will help. I hear you about the temps, my 6'6" 38 yo son is in Boca and complained about the heat to me just yesterday.
-
Yeah, I'm still sick and trying to do some things that I can handle. It's a mofo to be sick and out in 90* temps trying to do this stuff. LOL.. I still think if I gotta take the intake off I'm gonna do it on a car in the junkyard first. Just don't trust myself. LOL.. No, I don't have the video.

2002 Seville SLS Stalls While Accelerating from Stop
BodybyFisher replied to bruegelpie's topic in General Cadillac Forums
Have you checked for codes? Post all P codes here. P codes will help direct us. I see JAN asked about them but don't see a reply from you. 2002, did have CAT problems but that wouldn't have gone away in the warm weather Have you checked FUEL PRESSURE with a gage? I would test for fuel pressure immediately, if you can get a gage with a long hose, tape the gage to the windshield and see what happens when it stalls, and when you turn left Please post all P codes. -
I am less concerned with that, then I am about the 4 bolts connecting the spacer to the intake, and the oring. If we assume that the smoke test was legitimate, do you have the video, can you post it? I know you are doing a lot of work, it may make sense to pull the intake altogether with the TB installed, throw it on a table and inspect and work on it there, replace the oring, intake seals, look for cracks, etc. Let me know, Ill write a procedure and pull the procedure from the FSM
-
Yes, the ones for the TB..
-
@jndnaps you said above you didnt torque the bolts down, I assume you mean the throttle body bolts? I am speaking about the 4 bolts attaching the spacer to the intake, where the oring is located. Does that make sense?

2002 Seville SLS Stalls While Accelerating from Stop
bruegelpie replied to bruegelpie's topic in General Cadillac Forums
An update: The stalling issue basically stopped all summer, but has started stalling again now that the cooler temps have arrived. (I'm in Michigan.) The stalling is continuing, and is particularly bad when turning left. Car completely stalls and needs to be restarted. As I'm trying to determine if it the crankshaft position sensor, throttle position sensor or fuel filter, are any of those affected by cooler weather, which could explain why the issue went away this summer but is back again this fall? Thanks in advance for any help! -
Doing good thanks! Will document everything I do and report back. Take care!

The IAC on the right in the pic looks like the one it has. I've had the car for 13 years and the intake has never been off. I put about 45K miles on the 133K total miles on it. First time the TB has been taken off in those 13 years. I had the car at a local shop and a smoke test showed smoke coming out both sides of the intake. Shop thinks the intake is cracked, but won't know for sure till they remove it. OK.. Now the one thing I didn't do was torque the bolts down. I don't have a torque wrench. But, they're on good and tight. I don't have access to a scan tool. Yes, replaced the IAC with correct one and with the o ring.

Don't know...."94-97 were kind of bastard years....as GM migrated to OBDII.....Cadillacs lost a lot of the hidden features available thru the IPC. It was more of a question of is this GM vehicle OBDI or II?...a few GM vehicles had OBDII in '94-95.....What adapter do I need.....Do I need to use a VIM module.....etc. For me....it was never a question about using the IPC diagnostics...It was always "Am I going to use the Tech 1 or the Tech 2?" I always used a scan tool. A lot faster to do. 1998 and on.....it was very clear you were working on OBDII.

Battery drain

To eliminate the battery, first have it load tested to be sure it's good. Check glove compartment and trunk lights -
Cadillac Allante
BodybyFisher replied to ianhardgrove@hotmail.com's topic in General Cadillac Forums
Here is a 91 Allante code list and directions as to how to retrieve them. I dont see anything regarding the cooling fans.. I have a 91 Seville 4.9 Factory Service Manual, I'll look it over maybe it will be helpful. https://www.troublecodes.net/cadillac/91-92-allante-4-5l-vin-8/ -
@Logan I believe the 96 has the ability to display, real time parameters, does that sound right, I think I could do it on my 96
-
Most GM products....but not all older OBDI ones.... you can override the IAC using a GM Tech 1 or GM Tech 2. It has to be a bidirectional scan tool with the ability to turn stuff on/off to command the IAC. After OBDII......about '97..'98....pretty much everything had IAC control thru a GM Tech 1 or 2 for leak testing. Older cars without the scan tool ability to control...or if you have no bidirectional scan tool....you used the above Kent Moore tool.
-
This may be possible (commanded IAC) through the dash with the real time read outs I'll look into the commands
-
After you pull the intake, and replace the seals and check for cracks 😉😉

If this continues after you get it back together you need to get a scantool hooked up to see what the IAC counts are. If IAC counts are 0 and the idle is high there is for sure a vacuum leak. If IAC counts are high and the idle is high then likely the IAC is at fault. Was the IAC replaced? If it was was it the correct one?

ianhardgrove@hotmail.com replied to ianhardgrove@hotmail.com's topic in General Cadillac Forums
It is a 4.5l engine and the engine light is not on. I wasn't aware there was an obd plug on the 1991, so will check with the links you supplied to see if I get feedback. I will also take a look at the justanswer link as that seems like a possible failure point. Many thanks!! -

Hi Timt, Welcome. Your battery is draining over night? What year and model of Cadillac with which engine? Any other symptoms? Any aftermarket equipment installed on the Cadillac? -

94 Eldorado high idle/ no acceleration
BodybyFisher replied to Mekidbrat's topic in Cadillac Deville, Eldorado, Seville, Fleetwood, Sixty Special
You don't have an IAC on a 94 Eldo. You have an ISC, or Idle Speed Control. I replaced one last year on a 95, here is the thread there are good links in it also
