not a fuel pump problem. i changed the filter and drained the tank after i got the car. its not the tranny either, i had it up on jackstands and it ran all the way to 6400 rpm or so with no load. when there is a load on it , it surges not like a tranny going out, its reall bad till 3000 then it has a ton of power then it stops at 4000. i chaged the plugs and there was nothing left on 5 of them, im thinking that it ran rich enough for so long that it just clogged the cat, also the car had no muffler on it and it was as quiet as a stock alero, and when i cut out the resonator it barely changed the pitch, still quiet, so its ovbiously the cat. i just wanted to now if anyone gutted one? itll be basically open headers.
