So I've been dealing with a 0171 for a week+ now, already checked the MAF, plugs, new fuel filter, put a new EGR and DPFE on it too
Been thinking it's vacuum issues as the code ONLY comes on at idle
Also, during a cold start up, the code doesn't come on, but it's clear it's having a hard time idling and asking for more fuel
Anyway, I pull that elbow off the back of the supercharger (the one that runs to the PCV checkvalve on driver crankcase) and it's got a small crack in it. I'm suspecting that could be the issue
However, it that truly a vacuum section? I believe it's part of the pollution control valve and not positive crankcase vacuum?
Thoughts? I'm needing help and pulling what little hair I have left trying to get this fixed...
