I've gotta 2000 gt...now, when I try to rev the engine, it acts like it's not getting any fuel or something...so, I thought it might be the MAF sensor...so, I unplugged it, and it reved just fine...so, I replaced the MAF sensor with the stock one that came off the car (because I bought a K&N filter with a sensor on it--i had been running that one for a while)....anyway, when I put the stock MAF sensor back on, it does the same thing...but, like i said, when I unplug the MAF sensor, it sounds and revs great...any suggestions to my annoying problem?
