Hi all SVTers!
I have spent about 45 minutes reading the forums on "P0420" code for different and interesting ways of fixing it without spending $700 on a new manifold AND without spending the $30 on the "MilEliminator (crap). To be honest I am at a state where I really don't know what to do. I DO have another pre-cat from another SVT that I worked on and have not tried it yet. Now since the extra manifold is off the engine and easier to handle, would you guys recommend any cleaning solution that can be safe to use on the filter that's in the pre-cat? Like break dust cleaner, carb cleaner, high preasure steam, etc.
