Wasn't easy having a 2.8 but I finally changed my Electronic Coolant Temp sensor yesterday and holy sh*t, what a drastic improvement. I also cleaned out my air intake (there was alot of dirt inside) and now my car is running incredible. Just wanted to thank everyone who helped me diagnose the issue and giving me advice on how to install the part. Crazy improvement, feels like a new car!! This site is invaluable
