1992 Pontiac Bonneville stalls while driving

Sometimes it starts right back up couple times it was long cranking then started.

I have a 1998 bonneville that has been stalling once a week for 3 weeks now. Imine won't re-start right away, usually after about 20 min. No codes. I'm trying to figure out problem too. We have already replaced fuel filter and my cat converter was replaced couple of months ago. I think I may have in bad gasket at my intake manifold but don't know if that would cause the stalling.

After all the "guess work" of 4 techs, my problem is solved. It was the computer that needed to be replaced. So far so good no more stalling and starts right up! I had so many techs tell me their "findings" and none of them were right. The computer was putting out wrong codes which told the first tech TPS, WRONG! The reason the codes were wrong is because the ecm was bad. Finally, a tech, who I guess shows he knows what he is doing found it was the computer under the dash that was bad and replaced it. I think it is called the ecm. Well hooray for him. I sure have learned and I hope all you techs learn from this. I still stand by my philosophy, that if an auto tech really knows his stuff he does not have to go through all the false guess work diagnosis but rather find the real problem. My story is living proof that my theory is correct. I found the man.

One more thing, I am a woman and not an auto tech. However, I think a lot of diagnosing a car repair problem, is good listening, good communication, in addition to knowing what you are doing. Also a great deal of common sense is involved, as is living proof with my problem being solved. It is dumb to keep putting parts into a car costing money and time just to find the problem by process of elimination. Does that make sense? One guy even told me it could be my ignition switch. I cannot deal with "could be" as I do not have money to replace parts that are not needed in the first place. Now if I add up all these false diagnosis from all these auto techs by putting in all these parts, I would have put in a fortune that I do not have. It was not the ignition either. That is plain nonproductive. Auto diagnosis should not be guess work. I could not believe it when he said the computer was bad after I had my car towed to 4 auto tech places. It is just stupid to keep putting money and parts into a car and it does not fix the problem. One more thing, he showed me on the bad computer when he tapped it with a screwdriver the car stalled, so it was an intermittent problem, FYI anyone that is interested. So, common sense and good listening, and skill prevail. Thank you and Amen.

Thanks Tim. I tried to leave feedback but apparenlty have no points to give. I will try crank sensor next time car stalls. I have had my 1998 Bonneville for almost 3 years. In that time had hydro-lock twice then the cat converter was plugged and I had absolutely no power. Thought I was going to have to push it up hill. Now this random stalling.I got this car 'cause it had 3800 motor which is what is in the '91 Parke Avenue we bought my daughter when she was 16. She is now almost 22 and the car has over 220,000 mi, she's still driving it and we've had very few problems w/ that car. And minor to boot.

Did you read my post? Try your ecm

Well it fixed my problem. Oh, you mean spend more money to the tech unnecessarily by trying this fix and that, and spending on parts and labor till you find the real problem? Hehehehe
