Contact cleaner. sometimes it will scrape the contacts clean just taking
it on and off a couple times but the cleaner does a better job.

Actually I meant to say the TDC sensor.

Ah..ok...

Well..I looked. the sensor itself is on te driver side it seems (it
looks like the same thing as in the shop mnual.
However I see the wires go from the sensor, over te bell housing the the
passenger side where there is a connector that hooks it up to the harness ?

thanks,

Ron

Well.... could be. Most of the other references have it on the passenger
side and I sure gave a good look there for it.

After taking a break and looking around underneath we found it on the
driver's side and the wiring ran up to a connector on the intake manifold.
