Re: If you have an 01+ 4.0 with lean codes (PO171 and/or PO174) look here!
Could anybody possibly help me out with finding this elbow or another of the same type that could be causing this problem? Out of the blue last night my truck started idling way high and would go on its own in first or second gear. All I have read on here in multiple posts are that it could be a vacuum line problem or this crack in the pcv elbow. My grandfather who is a mechanic told me to check the vacuum lines and I have been looking and I can't find anything, I just don't know exactly what to look for. Any help would be appreciated. I am also worried I have an exhaust leak the exhaust welds from the p/o don't look all that great to me and seem kind of spotty. They also didn't even put the rear o2 sensor back in.
