don't know if you still need this, but i do and other people might, so i'll post up what i know. i did a little reading here:
http://www.asashop.org/autoinc...s.cfm and also did some searching on this forum. the PVCV is located on top of the engine plenum towards the back of the engine compartment. there was a TSB released to replace the older ones with updated ones. that little solenoid is a big failure point in these systems, so you may want to check it out. anyway, if anyone else wants to add more information we're listening!
