Default New Guy with problems

Hi,

She won't idle with A/C on!?!?
I know, don't run it! But... (very Hot Here)

There are many mods to my 95GT triple black. Cold air intake, Vortec at 12psi, Ford Motorsport intake, Performner heads, mild cam, headers, off-road pipes, Flowmaster. Lowering springs, Mac upper and lower control arms, aluminum driveshaft, 373 gears, 98 cobra wheels; 245/35 front, 255/35 rear.

I think that is most of it... Why does it stall when I put the clutch in with A/C on. And why does the exhaust 'load up' with raw fuel when I down shift, man what explosions, suprised Homeland security hasn't pulled me over.

I'm guessing computer??

Any suggestions would be appreciated.

Steve

you're guess is probably correct...do you have aftermarket fuel injectors? if you have a flasher module (sct, diablo etc.) cycle through allthe parameters and make sure the compy knows what's actually there

o god man lol idk about the idling thing but having aftermarket injectors with no flasher is a defenite NO NO lol that would explain your gas in the exhaust problem....i suggest the SCT Xcalibrator 2. You'll also wanna flash the comp for your bigger tires else your speedometer is off. You had that supercharger installed professionally right?
