1990 Pontiac 6000 LE 3.1L Poor Idle Quality, Surge
Posted to GM Driveability on 10/18/2001 7 Replies

This car runs like a vacuum [...] counts on scanner are 25 but the iac is all the way in(blocking iac port doesnt slow idle down any).Block learn wasnt this high before new injectors were installed. Injectors have been verified right and all drop the same fuel...
