1999 Dodge Ram 1500 Laramie 5.9L Poor Idle Quality, Misfire
Posted to Chrysler Driveability on 9/23/2005 14 Replies

misfires upon cold start. sounds like vacuum leak when iac opens, iac changes and misfire goes away. can put carb spray over the chamber and the miss goes away. this is why the iac was replaced and all adaptives reset. any ideas would be much appreciated.
