My friend just got done putting on his pacesetter headers with the high temp coating. After driving around for a bit we retightned a few things and was done. Hooked up to scan it and see where we're at. His IATs were at 114*F! Ok, well maybe it was just heat soaked from sitting there for a bit and went for a drive to get the air circulating. They were still reading 110-114*F. Allright, I was going to put on a different intake when we got to where we were going. Put the new one on (same thing I have on my car) as a half fwi/hai and took off the IAT extension and moved the sensor back ontop and in front of the tb. Well, the temps now read 76*F when it was ~70*F outside. Ok, cool. Get going and on the drive back to the highway they start to climb up and peak at 110*F. Get on the highway and cruise at around 70mph and the temp doesnt go below 102*F. So, we got off the highway and went to the autoparts store that was right there. Threw a new sensor on and it still does the same thing. Its not the scanning program or the intake as I scanned my car ~2 weeks prior and the IATs read within 5-10*F of ambient while moving. Any clues as to what it could be?
Edit: he also has an 01 Regal GS
