I was wondering the same, and if the intake temp sensor had failed, but I don't know how LR computers think, so I couldn't say.

No, I don't have those.
And yeah, one thing at a time.
They will be next, if the coils don't fix it.
I'm not optomistic on the coils fixing it, but, considering the age, and heat the plastic is constantly subjected to, I would think a fine crack could develop, especially after handling. And they do fail. At least I'm going to talk myself into it until proven otherwise, lol

Finally, some codes!
P0117, temp sensor.
The plug wasn't on well, clicked it on, temp light on dash off, needle functioning properly. I blame the dummy who put it back together.
It cranked and ran smooth for about 20 seconds, and cut off. Now it still will not idle, and the miss is still there.
Made me feel a little better, as I had 2 problems, and they are unrelated. So, some progress.
Still no misfire codes or history of. It does say,
Fault 108 continous power supply interuption.
With no letter to reference, I am unsure of the cause.
P108 is the mass air flow sensor, and could very well be the problem. B108 is a short, and no other letters are legit codes.
Does the 108 mean a bad ground? Which also makes sense.
Too many late nights.
Any input is appreciated.

I had a "continuous power supply interruption" code after my HG job. Apparently it just stuck around after I had removed the battery. I cleared the code and haven't seen it back since.

I find it strange you aren't getting any codes at all. Is the miss just something you are hearing or have you seen the miss counters increment on your hawkeye?

Just throwing it out there since its not electrical, but have you checked the throttle cable to make sure its adjusted right? I would think if its not adjusted right you could have a problem with idle that might not register a code.

No, no msfires, no other codes, throttle cable is fine.
Miss is definately present.
Did not clear up after thermostat opened.
Have disconnected battery, cleared codes.
Problem remains.
Thank you though.

Since you discovered the coolant sensor wasn't connected right, have you checked the connection to the Camshaft Position Sensor on the front cover?

I have not.
The sensor bolts in, and I remember clicking the connector on...but, that doesn't mean anything either.
I hope I can reach the plug with everything assembled.
I will check that tonight too.
Thank you
