Stalling Problem

I have a stalling problem that can't be figured out! My car is an 1989 cheverlet corsica (automatic). I have run a diagnostic and no codes have come out. Usually after driving for an extended period of time and/or at a higher speed (50+ miles per hour), I start to decelerate and by the time I hit 25 miles per hour the car starts to run rough as if the car is not shifting gears fast enough. Then as I come to a stop and the car stalls. Sometimes it starts back up, sometimes it doesn't, it just depends on the length of the drive time. Otherwise the car drives fine. I have tried replacing the O2 sensor but that seems to have done nothing to resolve the problem. Could it be the idle air control valve or the throttle position sensor? Any ideas let me know.

Welcome to AF check this thread out. It should apply to your car.
It is a pretty common problem.

what engine do you have? i have a '91 Pontiac Tempest (Canada-only Corsica twin) with the 3.1 V6, also an auto, and my car does this ALL the time. last night on the way to a friends house, i was sitting at a stop sign with my hazards on for 5 minutes because everytime i would restart the car, it would die the second i pressed the accelerator. i tried running some injector cleaner through it, but it seems to have done nothing. i was thinking of cleaning the throttle body. i'm taking her in to get a new exhaust on monday, so when i'm there i'll see if i can find out what to do about it.

I have 2.8 v6 engine. Sitting at stoplights for five minutes is not fun, especially if it is a high traffic area. I feel your pain. I have tried every kind of injector fluid there is and it does not work. I actually have my car in the shop right now. As of now they think a torque converter is sticking in the transmission, but they have to take the transmission out of the car and take it apart to find the exact problem. I should know on monday what the problem is and I will let you know.

UPDATE!

i managed to cure the stalling problem on my 3.1 V6 last night. all you have to do is disconnect the plug for the TCC Solenoid from the transmission. afterwards, my car felt completely different. no more stalls, better shifts, less "chundering", and the car feels more responsive as a whole. give it a shot, but consult a manual first to locate the plug on your car.

Please don't leave it unplugged!! You will overheat the trans and burn up more than just a simple TCC solenoid. I have read through most of the threads concerning this issue and unfortunately you do not always need the trans overhauled, in fact I never have done one for this. Have the solenoid replaced and have the trans serviced and or flushed. This will save you big dollars in the long run.

I ended up having to fix my torque converter, which unfortunately meant that I had to pretty much have my whole transmission taken apart and put back together. But there is no more stalling problem so it made the whole thing forth while. So now I don't have to pray about not stalling when ever my car comes to a stop!! :frog:

i've read in magazines and on other chevrolet web boards that there is no effects to leaving it unplugged except for a small loss in gas mileage.

And I've seen the results of those that do. It's up to you but for a simple repair I don't see where it is worth it.

I checked blackbook and your car sells for $6000 if its is X-Clean(really good condition), 5000 if its CLN(above average), and 4000 if its AVERAGE, 3250 if its ROUGH.

jesus...i was going to sell it for $700 OBO. i checked around (autotrader.ca etc) and cars in better condition then mine were going for $1500 CDN, so i compared mine to theirs and priced accordingly. i've decided to wait to sell it though. something happened where i needed to spend a large sum of my "new car" fund on an emergency, so i'll have to wait a while. thanks for your help though.

Sounds similar to a problem I was having. My car would stall before I even made it out of the driveway. Turns out I was low on tranny fluid...go figure :P
Also since I'm too lazy to read the entire thread you may want to try the idle relearn procedure. Start the car and let it sit in park with the e-brake on until the cooling fan comes on. Turn off the car and restart it again and wait for the fan to come on again. Should be set after that. There is another method but this is the one I've read about and use it and it works fine.

:bloated: No chance of getting 4000 for that, thats insane,
maybe 1200 for it, if your lucky...and you wont sell it with that problem, unless you sell it to a sucker, who has no idea how to look over a car.

Unplugging the TCC will not harm the torque converter. There are people that have been running without the TCC for years without any problems. The only drawback is you might lose 1 to 2 mpg.
The TCC problems is very common on the corsica, all engines, all models (LT, LTZ even). It is best to get the TCC replaced, but not a must do now thing. One of my '90 2.2L LTs' has had it TCC disconnected since 2000 and hasn't even coughed.
