Hi: I own a 1991 Buick Park Ave Base Model 3.8 V6 engine, I had problems with the car cutting off while driving. I went to several mechanics this is everything I had changed and the problem still existed. Mass airflow sensor, Coolant temperature sensor, Crank shaft sensor, Idle control valve sensor, Fuel pump relay, Fuel pump, Fuel pump strainer, Fuel pump filter, Throttle body cleaned 100%, Spark plugs, Spark plug wires, Coil pack, New battery. I had all these items replaced because when the car got a little hot or even sometimes all the way hot it will still shut off, like I turned the key off myself. No code never came on at all. But I spoke to a mechanic that is a retired GM Master Tech and he checked manually to see if the Coil Pack had spark, and it did sometimes. Then he did a manual test again this time with the master tech diagnostic computer hooked up and finally a code 42 came on several times. I then went and purchased the IGNITION CONTROL MODULE and when he changed it the car started running 100 plus percent like it was brand new all over again. And he also showed me on the old IGNITION CONTROL MODULE where it was over heating and melted. So please have your mechanic check the inside of the IGNITION CONTROL MODULE because sometimes it give a code and sometimes it don't but it will most likely be the cause of your stalling. Check it first before you go and spend hundreds of dollars changing parts that don't need to be changed. My lesson learned as a owner of this vehicle. I hope this post will be a help to someone.
I just got my '91 Buick park avenue with 88,220 miles. It turns great and drive amazing, but unespected turn off when you are on stop or going up slow, of low driving. But do not occur all the time. Please tell me something if you know what could be. We think is an electrical problem somewere. Thanks
this has been a great car, love the smooth ride and and comfort. had AC probs, charged system, now blower seems to blow low,even with it on high, and sometimes has fits and blows high then low. not sure if it's in the switch to fan or fan motor itself. any clues as to why this occurs?
The most solid car I have ever owned. If they still made them I would buy one in a heart beat. Very reliable. Car has 310,000 miles runs like a top
