Used a FLIR Camera to confirm that the temp was normal in initial tests and that the Thermostat was opening and closing properly. This led to the first couple of ECT sensors that were used, they were also tested as well as the harness was tested. It's possible that because of the intermittent...

Solved the bubble issue. Turns out there was a pinhole tear in the upper hose. However, the problem persists despite being vacuum bled. I showed the video to a local friend and we tone tested the engine harness from the ECT to the PCM again. I found no issues and the ECT is reporting the...

That's true that's true. The only thing that doesn't make sense is the lack of HC's being detected. But I'll test that again tomorrow. Either way, the engine is on borrowed time. After 150k miles I think she's just tired, and all I'm really accomplishing with fixing this is pushing the rebuild a...

Spent about an hour exploring some thoughts from the above. Still getting a similar result as the above video with air seemingly in the system. I spent about an hour with the cap off on the system and used the rad fan to keep the coolant from boiling, but hot enough to keep the thermostat open...

Just an update/bump for anyone interested. Problem persists. Replaced the ECT and the Thermostat with working units from another car to run some tests. Temperature fluctuations still present and in some cases vary wildly from 160 to 230 while cruising. in some cases enough to trigger a "cold...

Can't hurt. I've cleaned it a few times already. maybe the connector pins are corroded in places I can't see.

Sorry for the delay @macdiesel Yes it was. and it holds plenty of pressure with no loss. it was also HC tested and no HC's were discovered

Makes no difference. I figured if the heat was swinging aggressively as it was, I would feel a drop in the cabin heat somewhat, but nope. Same with if I leave it on or off regardless. This is partially why I think it's PCM or Harness related, having serviced every other part. And to my memory...

I can't seem to get a consistent fault wiggling any part of my harness. I just spent about an hour shaking and examining what I could and there was no fault detected, engine warmed up to 187 in about 10 minutes, however, after a brisk drive and a break to have some lunch, starting the car a...

I read both of your posts Both the continuity check in the loom, the condition of the ECT plug, and the connection to the ECU are in near pristine condition, no pins damaged no pins pushed out, everything clicked and tight. Wiggling the wires also doesn't seem to prompt the issue. I responded to...

I mean. I'm out of options at this point. I've followed the FSM procedure to bleed the coolant on the vehicles of other speed owners, but I've never had this issue with mine. I've been as far as having jacked the car up as well, but I suppose I can try the airlift and see what it finds. The...

Hey there folks. Wanted to bring up an ongoing issue I've been having for the last few months with the hopes someone here has insight into my situation. A few friends and I have been trying to narrow down the issue with myself and another's P0126 (Engine coolant temp threshold) problem for the...

Hey folks. Kind of perplexed at an issue I'm having. Trying to narrow down what it might be. Noticed this sort of happening gradually, but today seems to be the biggest problem day I've had. Having trouble getting the shifter out of gears intermittently. Clutch fully depressed, at times, the...
