Originally posted by gadget73Yes, they do get nasty. You can try cleaning it with carb cleaner, then spraying it with penetrating lube to un-stick it, but its possible that the IAC is bad and will need to be replaced. Try cleaning it first.
The IAT (intake air temp, also called air charge temperature) will affect idle, and fuel mixture. Clean it first, since often they just get coated with goop. Its in the lower intake manifold on the #5 intake runner.Passenger side front, behind #5 injector.

When they get out of range, usually you can tell because the idle surges up and down. If its not doing that, don't fool with it.86 Lincoln Town Car (Galactica).

when the air temp sensor went on my bros 91, when starting it would go high for a sec and idle down right away.

I'll concentrate on cleaning the IAC, and see if it will warm up without my help. If it does thats good. And I'll rund a scan test on it to see if the EGR valve is working correctly too. I will let you guys know tomorrow.

Let us know what code or codes you're actually getting on the EGR. Different codes mean different likely problems.86 Lincoln Town Car (Galactica).

And also, I got a 'Coolant Temperature Sensor out of range' Code 21. Which is bull because I just replaced that. I think it may be the wires that connect to it. Because, for a time, after I replaced it, there was no code. So I think it just may be wires.

Gentlemen! (and ladies) No more emission codes!!!!!!!!!!!!!!!!!!!! Idles like a champ. Still a cold starting problem though.
Only code left is the Coolant Temperature Sensor Code. Would that code come on if it didn't have or get enough coolant to the sensor? I still think it's the wires but I just want to know if that would do it.

It wouldn't be related to the coolant level. You can meter out the CTS to see if its good with a multimeter. A bad temp sensor can also be related to the cold start trouble.
So what exactly did you fix/replace to clear the codes?86 Lincoln Town Car (Galactica).
