Yes, checked connections at both ends. I have continuity between ECU plugs and sensor plugs. I separated and insulated the circuits in the harness, even though I found no damage to the insulation. Seems to have done the trick, as far as testing with an Ohmmeter, I no longer have any continuity between plug terminals. See how things go after I put it all back together. Problem could be deeper in the harness than I dug, Might have disturbed whatever was causing the issue. At least if the problem reemerges later I know I don't need to take out the Manifold.
