my van would run like it was trying to flood or miss after taking to my dealer where we bought it they shop man said it was the pcv that had failed. a weak later and 1000 dollors later we got our car back outher than that we are happy with the van.
The first time the pcv had a small hole causing mpv to shake violently at stops and idle very rough. Replaced pcv for $20 easy job
Engine light came on and the dealer is getting 2 codes. 1). intake shutter valve/timing issue I think..2). PCV Valve needs replaced. Total cost $377.20. I just had the coolent tempature computer card replaced over $700 of work. Yikes.
