well for starters on A) Yes jsut replace the purge valve you can find one ranging from 30 - 60$ on the net. as for B) just ask the gm dealership where it is and do it yourself. You can ask for a schematic of its general location as well which should be helpful. and as for C) no probly not it only requires 1. D) the ecm update there is nothing you can do about that they won't be able to remove the update and about the only good it will do is probably give you better gas mileage i could be wrong and you can always ask at the gm dealer.

It was torture but I got my money back. I had to TELL GM their warranty coverage as mandated by federal law. What a pain in the rear, perseverance pays off!

cheers glad you got it resolved hope my info helped. Leave it to the dealer to try and weasle every dime they can out of you. this is why I do my work on my own car myself, or take it to a mechanic i know and trust.
