Converting from EFI to Carb on my '94 Cobra - Need Intake and Carb suggestions ASAP!
I've spent weeks trying to get the car running right. It won't idle down past 1400 RPM without going into a radical lope, i.e. searching / hunting, until it stalls. I've got a TwEECer and Zeitronix wideband on the car. Been on and off the phone with my tuner. Made a thousand adjustments to the tune, ISC screw on the T/B, adjusted the TP, messed with the IAC, etc. Lost ground on the TP, ran an auxilary ground wire to the firewall. O2 sensors are losing voltage. Don't know if its an electrical problem, PCM, IAC, MAF... Drag racing season is HERE and I'm tired of working on the car. (100% burnt out) /End Rant
OKAY. I'm ordering a carb setup THIS EVENING. I need your suggestions!
