A potential suspect in my car's "spoof-spoof" phenomenon is the fuel pump. It only spoof-spoofs at 3500RPM and above, and anything below that, it works fine. My question is, is there such a thing as a partially-faulty fuel pump, which operates fine at certain range of RPM, and starts to fail at higher RPMs?

My mechanic commented that it is impossible to even drive a car with a faulty fuel pump, how true is that? What are the usual symtoms of a faulty fuel pump?

Will appreciate all your advice, thank you!
