it says something about running below thresh hold or something
P0420
ive ben told its the rear o2 censor because of my HFC...
i need to get the spacer thing to make it sit higher

 

yessir you're talkin about the antifouler mod. you can use spark plug antifoulers to trick your O2 sensors. i'd try searching for that, i'll do the same and see if i can come up with somethin for you
