Anyone else had issue with this? My tech researched my high idle and rough shifting out of park and came to the conclusion that its most likely because of this. Only problem is it'll cost me about $150 to have it diagnosed. But anyway, good day for my VX. She got new pvc valve, new air filter and Mobil1 synthetic oil change. Oh, and the tech said he also cleaned the MAF and sprayed the intake manifold for me for free.
