Slight power loss problem
I bought my truck about a year ago, a EFI 22R. The truck has always had a "lack" of power, but I've noticed that when I first drive the truck (cold) it seams to have good power, but when the RPMs get to about 2200 it has a sudden loss of power and at the same time the check engine light comes on. Always at the same RPM and more pronounced when cold. I have replaced the timing chain, PCV, cap, rotor, wires, and plugs with no change. I have also changed air filter and cleaned the MAF sensor. Could the fuel pump or fuel filter cause these symptoms? Or O2 sensor? Any help would be most appreciated.
