Is the temp gauge in the dash working ? Normal readings ? If so I'd look at the intake air temp sensor as well. Both temp sensors are negative temperature coefficient type and have the same resistance curve. You can compare them with a simple ohmmeter, readings should be in the 100s of kOhms at -40C and around 20kOhms at 10C.

 

Now I never said replace it I was going to give you some tests to do to see if it was bad.

 

ok still gonna

 

That's fine I just didn't want you to think I said that
