help!! stalling issues

jjreece · June 4th, 2010, 10:51 PM

hey guys, i'm new to this forum, as i just picked up my 1994 mustang cobra a few weeks ago. it has an intake, bbk h-pipe to flowmasters, e-303 cam, underdrive pulleys, short shift kit and upgraded ignition, i think those are all the major mechanical mods, anyway, the issue i am having is that anytime i'm stopped with the ac or lots of accessories running it will stall out if i don't watch the tach and feather the throttle. i tried cleaning and checking the normal culprits such as maf, iac, etc, and all is well. the car runs great other than this minor annoying issue. i was thinking it might be the alternator, but it reads normal voltage, and i have had no charging issues. any help would be appreciated, thanks guys!

MY guess might be the under drive pulley and cam might just not be puttin out enough RPMs at idle and your shit stalls???

I thought that might be the case too, but idk, the guy I bought the car from said that when he originally put the pulley kit on, the pulley for the alternator was too big, so he had to replace that one with a smaller one to get the correct charge, but it charges fine now, and the volt gage in the car reads normal when running so idk, lol

Its not the underdrives. More than likely its the cumputer trying to compensate for the cam upgrade. the cobra ecm is finicky

just a follow-up, I changed the fuel filter, and that seemed to be the prob, cuz now i can run the ac, lights, radio, etc, with very minimal idle fluctuation. I think a good tune now, and I'll be set, thanks for the input guys!
