Well the work was done in February. So, lol it is. I have poor gas milage at times. No codes. Changed fuel filter. Have good power no stalls, quick starting. I have a brand new boss upper plenum with the sensors, new OEM Ford, slap onnnew egr, and see what happens, any advice?that was quick.lol
An OBD 2 scanner would be a very good investment if you do not have one. You could monitor the sensors and fuel. The O2 and coolant temp sensors would be the first 2 things I'd check.Josh, having new problem, can't get site to post new thread. Friend smell fuel in exhaust and there are no codes.
