Carb Problems (Long)
 

Ok, here's the setup:

1993 GT
Stock 302
Lunati .512 Lift / .288 Dur
Edelbrock Torker II Intake
Holley 650 Double Pumper
Mallory 3 Port Fuel Pressure Reguator w/ Bypass
Stock in-tank Fuel Pump
MSD 6AL Ignition
MSD Billet Distributor

Here's the problems:

First off, the car will not idle when it's cold no matter what. This I can live with, but the main problem is the idle after it warms up. I can stop at one stop sign and it might idle at 1000RPM, the next stop sign at 700-800, and another it might die trying to idle at 200. I have checked for vacuum leaks everywhere, nothing found. The idle mixture and float levels are set correctly. The fuel pressure is set at 7 PSI (I have experimented with Pressure ranging from 3-12 PSI).
I hope I have given enough information for someone to lend some help.


Problem #2, I want to keep the A/C operational since I drive 50 miles to work almost everyday. Since the Computer and Harness are gone, I am going to have to manually wire up the A/C system. If anyone has accomplished this, please let me know.

Thanks,

with the carb...i had the same EXACT problems on my old car, with the same EXACT carb. i rebuilt it, changed every vacuum line... i tried everything. never got it working right. the only thing that fixed my car was getting rid of that Holley and getting the edelbrock. i'll never look back, never had one problem with the edelbrock...(knock on wood). as far as the A/C goes, i have no idea. never had to do that.
