So after diagnosing misfires a couple months back and finally getting my hands on the car again and getting all the codes cleared I found the one code that came back that's keeping my sisters 2000 Jetta from passing emissions. It was a P0112 which is an Intake Air Temperature Low Circuit. Description can be seen here:

So I'm going to jump to the conclusion that the IAT is bad. Going to replace that first and clear the code and hope that it runs better and doesn't come back. So I have been reading up on replacing one of these and it is saying the the IAT is an integral part of the MAF sensor. So does that mean that I'd have to replace both? Because I had my sister order the part from car quest and you can order just the IAT so I assume there is a way to remove it seperately. I'm just asking cause I didn't get a chance to look at it, and I want the job to go as smoothly as possible so I'm not standing out in a cold ass garage for too long.
