Welcome to electronic fuel injection, its not just ford.

And Im not to concerned with things being spelled correctly, but for the love of humanity use some punctuation and paragraph. That wall gave these old eyes a workout.


I had a bad ect once that shorted out and caused weird things on my dash gauges, most notably was my gauges would jump way up when ever I would turn the lights on or the heater fan and even when the electric radiator fan kicked on. My oil temp and voltage gauge would jump way up. So you could have sensor that is shorting out to ground.

FYI just because the check engine light does not come on doesn't mean the computer has not recorded a code. I would pull the codes any ways I promise there is one in there lol.
