Defouler Question
I just heard about the Defouler trick for the PO420 Code but i was told to find it at auto zone but the auto zone website said that they wouldn't fit my car. Can anyone send me a link of one that will fit my 00' monte ss? or are these things universal?

5/8" (16mm) spark plugs have been used in engines for quite a few years now, so that's probably what the stores have in stock. You need an anti-fouler for an older 13/16" (18mm) spark plug. The one I bought came from NAPA and has a part number of 730-2442. Maybe your local Autozone or O'Reilly can cross reference that number into the brand they carry and order it for you if it's not on the shelf.
