STALLING SOMETIMES WHEN STOPPING

Chevrolet Beretta

My 91 Beretta auto 2.2L sometimes stalls when I come to a stop while still in drive. If you put it in neutral it won't stall. The car has no problems when it is in motion. The first time it did this was about two months ago and then it had no problem until this weekend(5/7). What could be causing this and what can I do to fix it? I'm going to replace the fuel filter in case it is dirty and it a cheap part to replace too.

Replacing the filter prolly is a good idea. Just a thought. Check ur fuel pump and see if its holding the correct pressure. Does it still die if u give it a bit of gas to keep it going? Im not sure how you do it but it might be idling in too low of rpm and there is a way to change it to run a lil richer. Keep it from dying. If its already idling high and stalls. I dont know what kind of fix there is for that. Let me know if u find out cuz thats a problem my sister's '91 S-10 is having

My car also randomly dies when I brake and try to stop. I've replaced the fuel filter twice, got a new idle motor, upped the idle, new transmission filter and it still dies. I've brought it in to two mechanics about 5 times now. Any ideas before I just drive it into a river?

Have autozone check it for free. While ur at it. Make sure u have a good battery yet and ur serpentine belt is in good shape and looped correctly. Check your air filter for damage and dirt. Check anything that would be normal maintaince and make sure everything is done correctly. Some of these things i've noticed machanics over look since its either so simple or usually the first thing someone will do before taking to shop. Let me know what you come up w/ and i'll try helping some more if I can

Check the gap in the spark plugs and make sure they are correct. Look over your plug wires for signs of deterioration. Also check over your vacuum lines for cracks.

We have checked everything we can think of -- - filters, fuel pump, etc. All basics are covered. Have you ever heard of a modulator between the transmission and engine that may go haywire causing it to shutoff when the brake is applied? 1996 Beretta 160,000 miles

I had a problem with mine 89 itr would run fine for a while then when I stoped at a red light it would die and to forever ot get it running then I better be heading home it was my cooling heat sensor then my fan motor would mess up it was running but not all time it went out and my car overheated had to replace that too I also replaced my o2sensor map sensor fuel filter the map sensor controls the vacum make it run better take it to autozone or some one who can read the codes they are so many sensor on these car it hard to tell which one is bad my check engine light wiuld come on too when it was acting up the codes need to be cleared after fixing a few thing have it check again after clearing watch your temp gauge when it dies make sure it not getting to hot mine would die after going a little over halfway piont because the cooling heat sensor would keep my fan from running hope that helps

Well if this helps I had this problem out of two fords I owned at one point and what I did was dismantaled the valve body where the throttle is located and cleaned every inch of it. I am assuming that carbon & gum build up inside the throttle can cause stalling.
Each time i've done this I've never had another stalling problem.

I also personally like Dans Idea, checking the plugs wires cap or packs is a good start. Along with fuel filter the one connected the frame and the other one connected to the fuel pump.

Sounds like the TCC solenoid is bad it locks and unlocks the torque converter. Its on the valve body you will have too remove the valve body cover to get to it. The cover is on the far left side of transaxle

I had a customer that had the same problem with a standard tranny it was the prom chip. I would get the number off the prom that is in the car and see if there is a updated one to replace it. That was the problem that I found. Any GM parts dept. Can tell you if there is a update or not

I agree with keeptheberettaalive, but before you change that part, unplug it to see if that fixes the problem.
