Message	I would put in an OEM Coolant temp sensor. They are pretty cheap. If that doesn't remedy the situation Go through Ash's 6 P's of poor performance post in FAQ (Might be in tech). Also think about what else you've done recently, use that to figure out the first things to test. If you don't feel like doing the complete 6 P's I would try to swap out the PTU with a known working one, assuming you have a fellow Zer around, and do a boost leak test first. Good Luck.
