1996 GMC Sonoma 4.3L Poor Idle Quality
Posted to GM Driveability on 6/24/1999

Hey guys need your help. This vehicle has a high idle. While driving when depress clutch vehicle will idle high for 5-10 seconds. Problem gets worse when warms up. Cannot get vehicle to act up while in the shop. So far we have replaced the idle air control...
