1993 Ford Explorer Q&A

1993 Ford Explorer Question: My engine revs up and down while in idle and also shakes real bad at high rpms.

Could it be a motor mount problem? The idle problem is maybe a sensor or do I need a new ECU? because the cruise control doesn't work either. -
Answer 1
i think you should spend 100.00 and get a prof diag. don' guess its costly -
