Wiring to the ECT Sensor and the sensor itself looks good I don't have the tester to test the voltage on me. But near where the plug meets the wires it's electrical taped I peeled the electrical tape back a little and it still looks good

i'm starting to feel very strongly you have several issues going on.

ECT circuit only goes to and from the ECM. either the sensor is bad, the wiring is bad, or the ECM/ECM software is goofed. i highly doubt the latter.

MAF sensor as well as several other sensors share the same circuit for power with the o2 sensors. just throwing that out there, do not take this as a diagnosis.

Just checked out the underside of the air filter. I bet this isn't helping that's for damn sure. See the split? I'll test the sensor and voltage tomorrow when I have the right tool for it. In the meantime I'll put some high temp silicone on this. It looks like it was smashed in the hood.

That might mess with maf readings a little but it won't cause any of the issues you're having.

Your scan tool should display o2 sensor voltage.

Testing the o2 sensor voltage directly AND logging the voltage with the scan tool wouldn't be a bad idea, actually.

If both front o2's are switching and the ECM reports this, your o2 sensors are fine.

Your ECT sensor is fine if it is reporting the correct temperature.

Just a hair over 5 volts to the ect sensor. Not sure how to test the actual sensor itself.

The two things that are popping into my head at the moment is harness issues creating intermittent signals, or you have a problem with your ECM.

Also, are there any misfires? Poor/rough running at idle? Stuck closed or clogged injectors on bank 1 could cause a lean condition.

You said you already checked spark and plugs, correct?

It's a thermistor. It's 99% likely to be fine at this point.

Cleared the lean code today and it hasn't come back. So no CEL or codes now.

I just realized a metal clicking or ticking noise. Seems relevant to speed. I don't hear it when accelerating. only when Coasting down or driving very slow. Sound disappears when car isn't moving or is accelerating. It almost sounds like an aluminum fan blade being flicked. It only happens when the car is actually moving. It doesn't sound like a wheel noise I'm thinking maybe the rear differential ? It sounds exactly like a wobbly metalic fan blade.

Sorry. Lol. It's just my luck. Maybe the exhaust is just hitting a heat shield (the sound fits too perfect) I'll get under it tomorrow. The starting is still my main concern.

It's starting to feel like it. But I think I'm just getting fed up. About to go drag the damn thing to hell till something just completely breaks so I can fix it.

Not happening. Love it too much honestly. I'll figure this out one way or another any other suggestions for the start?

you've got enough problems going on where it might not be a good idea to keep diagnosing over the internet.

maybe someone in one of the regional forums can point you to a good shop that knows GTO's that can take a real good look at your car.

i think i remember you posting that it was your only ride at the moment... or was that someone else... anyway, if it is your DD, you might want to drop it off and get a rental, and eat the labor cost for fixing it. it just sucks driving around a vehicle with several nagging problems that you don't even know yet since it's new to you, trying to figure out each in turn.

Two bolts were loose on the driveshaft. One was super loose the other just a little. I'm pretty sure it fixed it.(the noise at least) Hard to hear the noise when it's raining but I don't hear it anymore. So back to the starting ?

I would heed NHJF's advice above. I think the issue is now well out of internet diagnosing, you need someone who can put their eyes and hands on it to fix. This thread is almost a month old with no resolution found, do you know Einstein's definition of insanity? If not look it up........

He probably never reconnected that vacuum hose behind the intake manifold.
