Idle problems

Babe · 01-13-2002, 10:05 PM

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?

You might want to clean your Idler Air Bypass with some Carb cleaner. BTW I hope you don't have stock injectors....

I've already tried to clean the idle air bypass but it only seemed to work for about 5 min. I installed an adjustable idle air bypass plate between the stock unit and the throttle body. This seems to bring the surge down to 200-500rpm. I've been told that an EEC-tuner will help me program the computer to recognize the blower but I want to be sure before I spend $700. And yes I do have stock injectors, Vortech claims this blower will work just fine with all stock hardware. Thanks for your help and let me know if you think of anything.
