    TPS and ICM Question

    I can only speak in general terms about what triggers a request for increased engine rpm, but the pcm uses the isc motor to perform this request. I keep a clean throttle body, but as we know, the Northstars tend to have clean exhausts and gummed up throttle bodies. Anywho, you will be surprised that even with a good throttle body cleaning, the valve to control the idle might be sticking and remain gummed up even after a tb cleaning. What happens then is pcm sends a request to increase rpm, the isc doesnt respond, so additional requests are sent where the valve opens to an extreme level and then the idle is too high. The pcm then keeps trying to lower it, in increments, but it is stuck at high idle. When the car is shut off or started, the isc motor becomes active where it successfully runs thru more extreme steps to increase and decrease idle and returns to its correct default starting position. Also, sometims after i shut my car off, i hear the throttle body clicking for a few minutes, and i traced it back to the isc. I never removd or cleaned my isc motor on my 96 Deville,, but you might consider that there might be some gum and tar causing it to stick and malfunction. I have removd and cleaned for other GM engines.

    Battery voltage swings

    I believe if it stays above 15v or below ~8.6v it sets the "SERVICE CHARGING SYSTEM" message. my car rides at 13.0v and i would not be concerned if its at 14.5 or even 15 for a few moments, but if it stays high or low for more than a few minutes i'd be concerned.

    Battery voltage swings

    I suspect you have either worn out brushes, or the common problem of sand and oil getting injested by your alrernator. One thing you can try is to disconnect the battery, rwmove the plastic shield, and metal access port, then using a small finished nail, stick it in the hole on the back of the alternator closest to the center shaft. Wiggle it a little to move the brushes, and free them if they are stuck in sand. Then spray some wd-40 into The hole to wash away some grease that could be holding the brushes back. Then insert the nail Again, and wiggle it. If you are up to it, you can remove the alternator, disassemble it, and clean out all the sand and oil from the inside. Use the finished nail in the hole to hold the brushes back as its placed back on the shaft. Be sure to mark the alternator prior to disassembly so you know how the two halves fit back in place. i either case, do not spray too much wd-40 as if too much floods the bearings, it could thin out the grease i side it, and cause it to get washed out of the bearing housing leading to a shorter bearing life.

    TPS and ICM Question

    Have you tried the isc motor? Could it somehow be getting out of position and raising your idle? I attached the procedure to raise and lower the isc motor from the dic. Maybe exercising the motor might help fix the issue or reveal if it is the culprit

    My 1996 LED taillight conversion

    I do not believe we have the can bulbs. I think that is what newer cars use. But I am really not sure. I ordered mi my make/model/year. I think you will be pleased with the bright lights. When in doubt, choose the Cree bulbs because they are the best.
  6. For the last few weeks, I have had a coolant smell, but didn't see anything. Well...... Today I had a whiff when I was driving, and when I got home I had a little steam coming out fom under the hood. The car never got above 196 degrees. The lower hose is bulging, and appears to have sprung a small leak. The radiator and surge tank were replaced 3-4 years ago as preventative maintenance. I never replaced the original hoses. Today I ordered a gates upper and a gates lower hose. Hopefully this is not caused by an overpressurized cooling system (if you know what I mean). I thought these were lifetime hoses? Do the nylon bands just break from age? I'll keep my fingers crossed with a ratchet in my hand when the parts come!!

    My DeVille Got Hit

    Sorry to hear of your bad luck as well. I will keep my '96 Deville in the garage on the trickle charger for a few more months. If life is any indication of this thread, they are targeted!! Yes, might have to get 2 cheap side cameras from China on eBay. I'll have to figure out how to keep the cigarette lighters always on.

    New Cadillac owner 97 Deville

    My rear hub went bad because my brake was hanging due to a sticking emergency brake cable. It's the only hub replaced, and under warranty, it was replaced with an oem unit. wonder if the rotor overheated and boiled the grease out the hub? when the wheel is lifted, it should not wiggle, and it should spin by hand. while driving, a bad hub sounds like you are being followed by an old crop dusting propeller airplane. While your suspect wheel is jacked up, apply the emergency brake. The wheel should not be able to be spun, and when the brake is released, the wheel should become free. find the override release for the emergency brake under the dash, so you do not have to start up the car, and put it in gear to release the emergency brake. This is not recommended if the car is jacked up or on jack stands.

    I have cameras in my cars. They shut down, and are motion activated. All of My blackvue cameras were expensive, but well worth the security. 4 years later, and the prices came down some.

    Just to be clear, the rear piston is not to be compressed with a c clamp. It requires the special notched tool or pliers, and the piston is screwed back to go inside the caliper. This is to support the emergency brake. The fronts can. Be pushed back in with a clamp or the caliper tool.

    I heard that running repeated hot to cold a few times followed by repeated heat to defrost gets the vent doors free by working them to extremes. It makes sense, but I never tried it myself. Sorry for stepping in, but it might be worth a try.

    Remote window controller

    Thanks. I guess there are no revisions, or backwards compatibility standards. Looks like I'll have to find out the particulars a little more. Devices made today are for the newer obd ii, and for the older cars, we need to go used, or nos.

    My dead Seville

    I am going to go out on a limb and say that after 10 years, the battery went bad and quickly drained itself dead. I am curious if you had alternator issues on that car? I was taught that a battery past its prime places a heavy load on the charging system. In either case, I am glad it's ok so far. What battery did you get? My garage queen has an optima.
  14. I purchased this on eBay: http://www.ebay.com/itm/Car-OBD-Window-Glass-Roll-Up-Closer-Controller-For-Chevrolet-Cruze-Malibu-Buick/292159785452?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 its a micro module that plugs into the obd ii port. I bought it for my sons new Chevy, but It does not say it works for Cadillac. I plugged it into my daughters ATS, and it works perfectly. When you get out of the car, and hit lock, just hold it for another 2 seconds, and it rolls up the 4 Windows. Hold unlock, and hold it and all the windows roll down. during the roll up or roll down, if you hit any button, it will stop the window at that place - so it is easy to open each window just a little equally.. I tried it on my 1996, and it does not work on dinosaurs. Apparently, Gm cars enable this feature in Europe, but it is not legal for car manufactures to have it as an option in the USA. If you have young kids or grandkids in your car, I would not recommend having this btw. can someone tell me when obd ii changed? I purchased a heads up display, and it only works in new cars. My 2002 Chevy does not recognize the device, and I had to purchase a new code reader because the one I used in my 2002 does not work in a 2016 car. I tried googling, but I could not get what or when it changed. I thought basic code reading would have been backwards compatible at least. ooh, and so you all know. They do make and sell $6.00 multi ports so you can have 6 multiple devices plugged into obd ii ports. And and it's like I tell my kids : it's all fun and games till I plug in another obd ii device and deploy the air bags!!

    My DeVille Got Hit

    To properly match/blend the paint, the front passenger door will need to be partially painted to blend the color. I do not believe the old technique of painting just a single panel is practiced anymore. The eye is focused on comparing the color match between two panels, but once they are blended within a panel, it is not noticeable. The paint shop / dealership should also give a lifetime guarantee on the repair work.
