engine sputters under hard Accelleration

[eaglebusa]

can someone please help me on this, i dont know where to look anymore.
whenever i step on the fuel, under hard accelleration, my engine sputters and basically dies. zero power.
we cant have a supercharged pontiac grand prix gtp (02) not pass a car on the highway now can we?

i have replaced the air filter, plug wires, catalytic converter and full exhaust. there are no engine codes.
it runs great unless i spool up that supercharger.

Definetly needs new spark plugs

[Scottydoggs]

what kind of plugs did you used, and was there a problem before the plug change?

[00grandprixgtp]

he says he changed the plug wires but no plugs i would go to plugs and look for the black crack LOL

Probably a vac leak.

Bet on it.
