alright back to go, it started acting up again here at lunch higher rpm, same grief. so I had a look at the wire running to the sensor, someone routed it up against the alternator, could be picking up rfi from alternator. 2nd issue, its a shielded cable and the braid down at the plug has been cut and folded back over itself about 3 inches up from the plug. could have been an rfi issue all along. should the braided shield be grounded at each end? and I also believe the 2 wires should be twisted not parralell, or maybe that's what the braid does. not sure how the wire is supposed to be routed but ill keep at as far from alt as possible.
