Hi, What did you find was causing the problem? Is the compressor OK? Was the check engine light coming on when it was running poorly?
Can you post the diagnostic code that is causing the check engine light to come on?
Have you tried purchasing the cam sensor at the Ford Dealership?
What engine do you have in your Mountaineer?
