so im having a problem where everytime i go to accelerate my car has no power between 1000-2200 ish RPM's!.. i have the push the gas in about halfway just to accelerate a bit... then once its over 2200ish RPM's i get all the normal power back and can accelerate.. once i stop again.. same issue.. any ideas? i thought it was fuel system related.. but now im suspecting EGR valve or catalist problems :S car keeps getting worse and worse!
