Hey Fellas, sorry for taking soooooo long. Work has been hectic, we've had alotta rain here lately and I run a small landscaping buissness so I had to play catch-up. I got stuck in the mustard, lol. Anyways 68C15; the codes that came up on the reader at advanced auto are; 1) = P0101 mass air flow circuit A , 2) P0300 = random multiple misfire , 3) P1406 = EGR pintle position sensor circuit. Those are all that came up, (this time!). I am off work and home today, I,ve pre-purchased the gaskets and nutz n boltz for the cat. converter and will be pulling it today to determine if it will be re-used, re-placed, or re-worked, (indian style, = drive a pipe thru it, lol). I'll post the results tonite for more opinions, questions, or sudgestions. thank you all for the help.
