So good news valve did not hit. And thats about all the good news i have... it now idles... still have p0108... map reading is 4.4v i know this is wrong. Could a back fire have messed up the sensor? Long term fuel trim at idle is -32% Vacuum is stable at 15 inches. (Might be a little better gauge is not very accurate) Every so often map will read .28v and then the truck runs fine... i know think i may have cause an open circuit? I luv dodge but man its one thing after the other on this thi
