Question about a PCV system. Problems with my Ford Expedition.?
I took my vehicle to a shop and was told it has a leak in the pcv hose and I had to order a new pcv system. My current problems with my vehicle are: rattling sound whenever I accelerate, misfiring on some of the cylinders and idling rough when stopped. And a loss of power when trying to drive up hills and inclines. Do all these sound like problems from a bad pcv?
