Help me help a friend as I have no knowledge of Explorers.
She is getting error codes PO171 and PO174 and doing some searches it seems many get that error with a leaking elbow connecting to the PCV valve. Does anyone have a quick photo showing what to look for that I could send to her?
I tend to think this maybe her problem as her Explorer runs like crap and she says the A/C duct flips when accelerating which is often a vacuum leak. Maybe fix both problems easily.
