i tihnk this may actually be a problem, originally i would occasionally hear a sputtering farty noise unde rheavy acceleration, i assumed it was water in the exhaust and dismissed it, but lately it has been doing it more often, and seems to be sapping power, it HAS been very raininy and mor ehumid so it could be a larger accumulation of water i suppose, but how would i fix it, and what else could it be?

My guess is spark or fuel. My initial inclination would be fuel pump, because that is what happened to me.

i had a very similar problem bout 2 weeks ago and i messed around with a few things and finally put some new plugs in it and now it runs smooth.

Sounds like your plugs are fouled. Or about to foul.

Just go grab a new set, gap 'em, and you should be all good to go.

what are good plugs? i heard the bosch platinum arent good on gm cars and have heard good tihng about the ac delco iridium

oh and whats the spacing?

Had a similar problem (and no boost). Spark plugs solved the problem.

I used AC Delcos. I think the gap is like 0.060".

I'm partial to NGKs. TR60s are stock heat range [stock, no mods]. TR55s are one range colder [CAI, exhaut mods, minimum].

.050" or .055" gap for either. Pick the gap you want..

i got autolite 605, they were spaced just under .060 but i spaced em to .060, since thats what the emmision sticker said, should i put em down to like .055? i havent instaleld them yet btw, waiting for the car to cool

Changed the fuel filter?
