I need you guys' help! Yesterday my dad put some anti foulers on my downpipe to try and keep the CEL off. Well, he took it for a ride yesterday and said it was fine...today I went to go to the doctor...and it's running like complete sh*t! As if an intercooler pipe is loose or something...all the vac lines are fine...all the intercooler pipes are fine...I'm lost...running like a charm one day and the next....crap...

Dezod stage 1 kit...10.5PSI..AEM f/ic...700CC injectors...blah blah....anyone think of anything???

 

Leak somewhere.

 

The anti-fouler needs to go on the second O2 sensor on the s-pipe. NOT on the O2 sensor on the downpipe.

 

Correct-o-mondo

 

Yes...second 02 sensor...and make sure to disconnect the negative battery terminal for 15min as well.

 

I didn't mean down pipe. I meant S pipe. I took the anti foulers off to just see if that was the problem...sure enough it's running like normal...I have no idea how that has sh*t to do with it..but it did.

 

Sounds like the anti-fouler might be leaking. Try putting copper silicone RTV on the threads before putting it together (both fouler and sensor threads).

 

Did you guys drill out one of the antifoulers to 1/2 inch? Should drill out the one that the O2 sensor screws into. Then screw that into the other antifouler. then the whole thing into your s-pipe?

 

Yeah, we drilled it and all. I just tok em off. MY tuner just suggested that I try it because with the CEL on it makes my car run rich at idle.

 

they wont get rid of ur CEL anyways.. just go back to what you had before the antifoulers
