Hi guys, on my 94 4.6l engine something with the temp gauge was wrong today. The car temp goes on the N or the O of NORM but it never did that, it always stayed behind the N so something must be wrong with it. I unplugged the coolant temp sensor and the high fan came on and everything was normal so i stayed with that until my check engine light came on. So i thought that was the problem. I replaced that sensor and still the same problem. Do you guys know what could cause this minature overheating? I going to change the t-stat and water pump today but i dont wanna spend that money if i dont have to.
