Idle problems
I'm hoping one of you guys out there can help me. I recently installed a Vortech A-trim supercharger on my 1991 convertible. Everything else on the car is stock except for Flowmaster 3-chamber mufflers. I can't get the car to idle properly, it keeps surging from 200-1300 rpm. At full throttle the fuel pressure reads 43psi and the boost reads 6psi, its fine at driving speed but it just won't idle. Any suggestions?
