my buddy just did sea foam....didnt put it in the throttle body it was like one of the hoses....

 

take the neg battery out. wait for like 30 sec put it back on . and you set

 

So this may ruin the o2 sensors huh? Will it ruin the cat as well?

 

alot of additives are bad for engine parts and the extra components attached to it... i dont see seafoam being an exception.

 

Fuck it then, I'm not killing my cat. I've been down that road before when I used to be a dumbass and used race fuel. Come smog day it failed horribly w/no mods. I played dumb and the dealer gave me a new cat, but shit if not it would have been a grand for a factory cat.
