Sorry, not a contour question, but girlfriend's check engine light is on. Reading as a camshaft position sensor. I imagine this is under the timing cover. Anybody know if these go wrong? I have a hard time believing their is a problem with it. The timing does seem to running advanced. I hear a little pinging now and again and it is sluggish down low. Runs great once on the highway. Only 80K miles so I doubt the chain stretched or jumped. Any thoughts? Ford is quoting me $195, assuming this is the problem.
