I can understand the IAC maybe having something to do with mpg! But how would the temp sensor affect mpg?
You know, this all started a couple of months ago due to a faulty fuel pump. I just seems hiddeous to me that everything in the engine all of a sudden turns to Sh!t! It has to be something simple! Every filter, gas, air, everything is new! No leaks in fuel system or hoses anywhere! Oh well, I guess it takes being ripped off by a dealership to find out huh!
