1990 Chevrolet Corvette ZR-1 5.7L Cuts out
This vette is having problems with the port throttle system. At times it will work ok but most times it will limit engine power to below 4k rpm. I have had the intake off a couple of times and all systems seem to check out, no vacuum leaks vacuum pump work...
