Ever since I installed my new T3 Super 60 and replaced the head gasket the car has been idling unusually high, between 1200-1400 RPM's. the car is a 1996 NG900 with just about everything modded. Other thatn the high idle the car pulls like a jet and runs the 1/4 mile in the mid 13's. I've tried cleaning the AIC valve and soap tested the vaccum lines with no luck. Any help would be much appreciated. THANX>>>>>>Blkturbo :evil:
