1992 Buick Riviera 3.8L Poor Idle Quality
Posted to GM Driveability on 11/21/1998

Hi Guys! I have a strange problem with this Buick. After a long trip, three to four hours, the motor won't idle down. Customer can't tell me what the idle speed is, even though there is a tachometer in the car because he is afraid to take his eyes off the road...
