Acceleration problems...not fuel pump or filter ?!
Hey everyone I just made an 1500 mile trip from UT to Texas and the 2000 B4C Camaro with 133K on the clock is acting up. When going up hills(after the car is warmed up) she feels like she's not getting any fuel. You can hear the pump working like crazy, and we just replaced the fuel filter. I'm not throwing any codes and I'm not in a financial possition to take it into a local dealer. Any quick suggestions? Thanks guys!

Cats have been gutted and I have brand new o2's fairly new exhaust and granatelli MAF(about 30k mi. old) whisper lid and brand new air filter(Fram).

Also run a fuel pressure test. Just cause you can hear it does not mean it is performing to par. Could have also gotten a bad tank of gas.

I did pull the codes and got the follow errors: P0171 and P0174 These are saying that both banks 1 and 2 are running too lean. Anything else? Oh, I will work on getting the fuel pressure tested.

I'd say you probably have a vacuum leak or some other source of unmetered air. Check all of your vacuum lines and the couplings for the air intake at the MAF and throttle body.
