Sounds like you have a severe vacuum leak, causing a lean condition. The car runs for a short period because of the rich mixture the computer provides for cold start-up.

You name it ive done it!!!! I have a 99 regal with the 3800 series 2 and it is running rough either at idle oe driving and every once in awhile it will just die but starts right back !!! any ideas?


I have a 1988 Buick Century and was having trouble diagnosing a similar issue. $70 and an idle air motor (really looks more like a solenoid-driven valve) solved 60% of the problem...still working on the lagging on the high end, but driving it every day. Good luck!

Buick sounds like a dying chicken


Do you have the 3800 V6? It sounds like a bad bearing. Most likely the tensioner pulley or alternator.
