BLUE- 2000 SS M6
best way to fix the cats
Well my 2000 ss M6 hit 82k. Now started to get codes P0172, P0175 and P0430. I had this happen about a year ago and finally traced it to a vacum leak in the cheap hose bewteen the PCV and throttle body. 5 cent hose fixed it.
Now the codes are back and I d'ont hear a vacume leak. Doubt both O2s would go out together. I did run a tank of Tecktron fuel injector cleaner and the codes showed up at the end of the tank??
If I can't clear the codes what is the best way to gut the cats and maybe but in a basic nitrus system. Is it hard for a very basic system? Car is totally stock and runs 22-24mpg so can't be too rich. Best track time a couple months ago was 13.999 with stock car and "touring commuting tires"
Now it is getting a little older I think I need to take it up a knotch. Can $600 do it if I do the work myself?

I would doubt your cats have anything to do with rich codes. I would assume you have something else going on there. Is the car missing at all? Any mods?
