Also another thing I have noticed, I replaced the tps, then removed the c101 with great results (as y'all know) but I noticed something. I would still get the occasional high idle. Checked my manifold bolts and used starter fluid to see if there was a vacuum leak, with no results. But at idle, my renix would be at 500 rpm cold, 600 warm.
This is what I figured, the motor in mine is 24 years old with 297k on the ticker, so I thought, well, the butterfly valve looks like its closing too good (imagine all the times it has opened and closed over the years, the plate wears down or the throttle body does, was not able to take measurements) so I decided to mess with the idle screw. Nothing drastic, just about a quarter turn to increase the idle to compensate for the wear inside the throttle body. I still have to readjust the TPS (because now it sits a little more open) but there is a problem it solved so far.
When the oil was hot and idling, pressure would drop to 0. Now mind you my renix was idling at 500 all the time, so my hypothesis was that it wasnt running fast enough to build enough pressure. Now, it will stay at 20 psi at idle reliably, but the idle is still a hair low. Just a little more tuning and it should be straight. Ill post again when I have time to calibrate my TPS because of of my probes broke (its a pos multimeter).
And cruiser54, I checked all of my grounds after the fact, and all of them read less than .01 ohms consistently. Will report back with more.
