04 f-150 FLUCTUATING RPM'S WHILE AT IDLE
I have an 04 f-150 5.4L that I just changed the plugs, oil pump, water pump, the variable cam timing sensors, the cam position sensors. It is fluctuating rpm's from 400 to 800 while sitting at idle and when I put it into gear it runs around 400 to 600 rpm's. The check engine light cam on and off and back on. But NO codes are coming up. Can anyone tell what else to do to fix this thing. Thanks
