jdmccright Thanks for your input all information is helpful as this is why we are on AF. I did a manifold gasket on the truck last year and broke the coolant sensor so as of July 09 it is a new one. I double checked this when this mysterious stalling started. Yes Sir I will check it again as I'm saving my last gallon of $2.79 gallon of gas for torching her and collecting the insurance-Just kidding, I have owned it since new and had never had a problem i couldnt solve until now..
