p0302pd & p0302 code--

Question

changed coil--changed plugs--changed injector--intermittent but seems to run rough and set code most often when fuel level drops just below a half tank--any ideas?--can a fuel pump cause this problem?

Answer 1

HI there,

Normally the fuel pump will cause a misfire on more then one cylinder. Sometimes the problem can be caused by a fuel injector that is partially plugged. You could try swapping this injector with the one next to it. If the misfire moves with the injector, then replace the injector.
