Engine Mechanical problem
1994 Saturn SC2 4 cyl Front Wheel Drive Automatic 90000 miles
Idle's rough after warm while in gear. In neutral or park, idle is fine. No engine trouble codes are set. New IAC valve installed and run on road 35-50 for about 2 miles. Couldn't hold exactly at 40 mph very long due to traffic. How long does the auto reset adjustment take for new IAC valves?
Evap canister and hoses look good, no vaccum leaks there or with EGR. A puzzler. This is a used engine I replaced about 30K miles ago. Does engine require a reprogramming of sorts @ a Saturn dealership?
have the same problem?
