Hey guys, I did a search and came across a thread that had the part numbers for napa replacement CTS's. I was going to link it but for some reason I cant copy and paste the link here? Anyways, Im looking for one for a friend of mine, the temp gauge on his dash works intermittently and were thinking its due to a bum sensor. He was sold one from a parts store, but it looks like the one for the ECU signal as it has the oval plastic thing underneath the two prongs. His car is an 89 so it has the two prong sensor, not the one prong like the 87 and below cars. Is the one from NAPA an ok replacement or is it really necessary to get one from mitsu? And are the one prong sensors interchangeable? THanks! Phil
