cold hessitation/stumble
I have an 87 Firebird with the MPFI Chevy built 2.8 V6
the problem is when the engine is cold if you crack the throttle the engine will stumble, buck a few times, make a popping sound like it backfires in the intake then it will rev to oblivion without a problem...and it only does it when cold... the car also Idles very low when cold on the order of 450-500 RPM
any advice would be greatly appreciated
