Okay, so about a week ago I had gotten some gas and about an hour later I was leaving the store and my car felt very bogged down. Around 3k rpm or so it would come back to life and run like normal till it fell back below and the car fell on its face. Also has rough idle and a "chugging" feeling.
Now, thinking maybe it was bad gas I ran the tank very low, added some dryer and changed the filter. The problem was still there but instead it never opens back up at higher RPM.
My latest attempt was a Trick flow 255 Fuel pump and I still have had no luck with the problem.
So I'd like to get some ideas before I spend even more money on parts and chance the problem staying.

But a hole was busted out where the hook goes up into the trans hanger, i welded it and it was fine but since this problem started i also notice a possible exhaust leak on the same side where the whole was.
i was told that by someone else as well. but i was told it could be a vacuum leak. but when i sprayed around behind the maf with carb cleaner the ideal never changed. so after that i thought it could be a fuel problem. so changed out fuel filter and spark plugs and that didn't fix it.
