Had replaced plugs,oxygen sensors,air mass meter,fuel filter and 2 coils # 3 and #4 ,codes stated that misfire where# 3 and #4 cylinders.sometimes it runs fine,and when you acceralate it feels that it starves and the picks up power.I hate to keep throwing parts at the car,my mechanic keeps reading the same code.What's next fuel pump,injector,fuel pressure reg.?

Hi there,

If your mechanic has the fault codes, he should be able to start a diagnose of the trouble area. If it is a fuel related issue i would be checking pump pressure, flow rate, rail pressure. as a starting point.
