I finally found my cam sensor and I detached the wires and sprayed with electrical contact cleaner as well as the gizmo that it's attached to above it that was loose and I tightened it. I'm not sorry I bought the oxygen sensor, worth 140,000 miles, because it got me a new code number, from 412 to 214 at Pep Boys (free code check). I also sprayed the MAFS real good, and anything else I could find. Drove the car 12 miles and no more Check Engine light for now. I'll keep my 1994 Escort LX a couple of years more now that I have a new headliner, detailed inside and out, 2 new tires etc.
