1994 Buick Park Avenue Ultra 3.8L Poor Idle Quality
Posted to GM Driveability on 2/20/2004 14 Replies

This thing will vibrate like crazy at idle. Come off and purrs like a kitten. I have no dead or low cylinders. It has done this ever since the engine was replaced with a used one about 8 months ago. Runs great off idle, and does not stall. Idles about 800 rpm....
