SO i finally got my trans changed out (for now lol) but after putting exhaust on it i have been having alot of issues with running rich (AEM Brute Force intake, Pypes xfm10 midpipes with Xpipe,Warlock Mufflers with Removable baffles is all thats done to is) i have changed plugs,wires,distributer cap,Rotor, run injector cleaner through it... heres the only thing the car idles fine and under WOT it runs perfect but spits gas and backfires constintly... any ideas on the issue????

PS the check engine light comes on after about 30min of driving and my right header leaks a little.....

google DIY koer and look for a link by joel5.0, no such thing as can't = operator error or in rare cases ecm issue but 90% of time such is not tthe case.

the light is non consequential for code pulling, its only need is to flash when you pull the codes it doesn't have to be on before or after. Most likely the only code you'll pull will be unimportant random ones and an hego code, sounds like sticking injectors (open) check fuel pressure while you at it.

Fuel pressure is 38psi and no injectors are sticking... also regulator is good

How did you test to see if your injectors are not stuck open?
What is the fuel pressure when you goose the throttle?
Whats your vacuum at idle?
Codes?

bench tested injectors (didnt care about pounds just to see if they where close to one another), dont know just checked with the ignition on and no throttle(pump put out 38psi) dont know vacuum will check...cant get codes wont seem to let me will try agian tomorrow
