Why does my 1991 Buick Park Avenue Stall while driving?

Answer 1

I have a 1991 Buick Park Avenue with a 3.8 V6...

sometimes when I'm driving down the road the car will randomly just die.

It completely shuts off as if I turned the key off, there is no sputtering like a fuel problem or anything like that, sometimes it does it as soon as I start driving and other times it takes 20 or 30 minutes before it acts up. Also, sometimes it will start right back up and other times I have to let it sit for 5 or 10 minutes.

I've already replaced the ignition coil pack, mass airflow sensor, o2 sensor on upper rear of engine, cam sensors and checked all my fluids and had 3 mechanics look over it with no clue why it does this!

the only thing else i can think of is maybe the ignition module under the coil pack?

or maybe the main computer itself?

Please help me out! this has been 2 months of frustration!!!

I have a 1992 Buick Park Ave. 3.8 V6 with the same exact problem. A mechanic told me it was probably a sensor getting hot, because everytime the car shut down on me I'd open the hood for a min. or so and it would start back up. If I didn't open the hood it take a little longer to start. So I'm kinda leaning toward the coil pack or ignition module. but before i replace either i've ran a switch to control my fans rather than wait for them kick on them selves. I also checked the OBD for trouble codes and one came up but was not in the book! 17 was the code. I'm at a loss for words. any body please give some input.

Long story short, spent 2 days on my sisters car ,a 91 Buick Century, that kept telling her she was hot ( the temp light lit off and on and the check engine soon light also and then it would die and 10 min later start again and so on. Turned out the coolant temperature sensor is not so good in these and goes crazy and then shuts down the engine even if its not hot at all. The first time it happened I was with her and the cap for the radiator was not even warm. Ten dollars for the sensor and 15 minutes to get the old out and the new in. It's located on the engine block just look for the 2 wire small screw in sensor. There is another sensor that will shut down the engine but you'll have to ask a parts place because I can't remember what it was.
