I am in the process of eliminating my sometimes miss and up and down erratic idle problem. I have not replaced my PCV's and know I will have to cut the hoses to replace them and need to know where I can get replacement hoses from besides the dealer. What size are they ? and what size is the vacuum hoses on the Z32 for replcement. Can i get the hose sizes from Autozone, Pep Boys, NAPA etc.

a couple of the hose vary in diameter from end to end, i suggest you suck it up buttercup and pay the dealer price. Your car will love you for it.
