Question

this code is telling me #5 is misfiring. Ive replaced Coil, Injector and Plug, Ive also replace head gaskets, had a compression test...all is well but car is still running rough, like a misfire.

Answer 1

Hi there

This could still be a wiring issue to the coil or to the fuel injector. Check the injector pulse with a noid light, and check the wiring from the coil and the injector back to the computer. If the wiring is good, it may be a poor  computer causing the problem.
