One of the wires was stripped a bit and showed bare metal. I "replaced" the connector (I massaged some spade connectors with pliers) and cut out and replaced as much of the wiring as I could, and dusted off the sensor and the spinning thing. This is THE FIRST TIME since three weeks that I have seen ANY (persistent) improvement at all.So now I am thinking - is my timing chain stretched? My camshaft position sensor out of sync? A retarded/advanced cam or spark would explain the occasional backfires on decel and loss of power, as well as the hesitation to start sometimes.Another thing I read on some other forums is AC ripple from the alternator can confuse the sensors. I did stab my battery with a DMM set to AC voltage, and it settled at 0.06v. So there is some AC ripple, but I don't think this is enough to trip up sensors?Now, as I don't have time anymore, I have to conclude this chapter for now. Once I get back I'm probably gonna hook up a scope to the battery and the sensors and see what is going on. But as for right now I'm happy about the little progress I made. I improved from massive traffic impedance to minor road hazard. So that's a win.

And absolutely not with the coolant temperature or the thermostat. It flows for sure. The same issue persists even with the engine coolant cooled down to a degree, and I am able to run the engine for extended periods of time without it seizing or puking coolant. The ECT readings are completely within check, and behave absolutely normal. I know this because I have run lots and lots of logs for all kinds of driving conditions and closely inspected them and compared them to known good logs.I think the heat just coincides with something. It might be a sensor giving more erroneous data once it warms up, or a timing belt slacking more once it heats up, etc.</blockquote>
