NC Iowa | it runs smooth, but just suffers from a real lack of power. at times it has normal power, but not often. it acts like a fuel problem. i changed the fuel filter. i was thinking low fuel pressure, but had it checked and was told it was ok (around 9-12psi). is has the throttle body fuel system. is there another filter or screen in the throttle body that might be pluged? mechanic said sometines a egr valve will cause it. hate to just throw parts at it, but might come to that. any ideas on things to check?
thanks. | |
