Well I either have a bad t-stat or a bad ECT sensor. What does it do and is it easy to replace?

Engine coolant temp sensor,,tells the ecm how cold or hot theEngine is..therefore adjusting fuel and spark control,along with idle...and on several it even uses this info to turn the Rad Fan on and off...

Thanks for the info. Where is your coolant temp guage at operating temp. Mine only read about a 1/8 to 1/4 of the way up the guage. I think its the t-stat. Has antone else had this problem. I am thinking of replaceing it with a 180.
