2002 Ford Ranger runs rough at idle but no OBS code?
My 2002 Ranger runs rough at idle. If I goose it a little, it goes into high-idle for a few seconds, but starts to run rough like it is lurching back and forth.
I have an OBS scope and there is no error. I suspect that it has something to do with idle air control.
Does anyone else have this issue?
Is this a good question?
