Check engine light came on. Took it to parts store, they ran diognostic. Came back as camshaft blah, blah, blah. Sold me part no. F153 (Wells), sensor. Told me it is applied to rear of head, for replacement. Well I've looked. Can't find the spot to replace it to.

Never mind. If you put your head against the center of the firewall and look down, there it is. Top of the engine in the center and behind the intake manifold. Oh yeah, keep your old screws, the replacements are 1/4" to short.
