New PVC Elbow = Won't idle
I have 2002 Ranger XLT with a 4.0L and I replaced that POS PCV elbow at the intake manifold, got rid of the PO171 and PO174 codes but now the engine won't idle and stalls in gear if you take your foot off the gas. Prior to finding the cracked elbow I changed the mass air flow sensor and the fuel filter, cleaned the IAC, checked and cleaned the PCV valve. The engine purrs like a kitten with the busted elbow installed, dies whenever I put the new elbow on. The codes usually come back in two days or so with the old elbow on and I can't drive it that long with the new elbow so I don't know if they will come on with that one or not. Fuel pressure was running a little high at 75 lbs. but I don't know if that matters. Any help would be greatly appreciated this has me and my mechanic stumped...
