Hey everyone,

So basically, I have a CEL issue and am trying to figure out the source of the problem.

The CEL only comes on when i'm on the freeway, just cruising, and even in neutral. It'll just come on randomly, and stay on. It is weird because it only comes on while i'm driving on the freeway, maybe something about higher speeds triggers it? Also, when I reset it, it will stay off when I'm driving around town, even if i go WOT it does not come on. In fact, todd at Church's reset it and it stayed off the whole tuning session.

Anyways, not sure if it is my Invidia test pipe or not. I would think that if it were the test pipe, the CEL would come on all the time. Any inputs on what it might be will help. Mods are in sig.

Thanks!

 

Did you get the code number?

 

i'll get the code and post it ASAP.

 

I would as you can never be to carefull, its prob that the decat needs a antiplug fowler, but you'd better check first

 

just got back from autozone, the code i'm getting is P0420. any ideas?

 

P0420 Catalyst System Efficiency Below Threshold (Bank 1)


my guess is a test pipe problem or your CAT if you still have it.

 

ok thanks

 

Yep I get the same code from my TP with a so called CEL fix on it. I need the anti fouler adapter.

 

where would i purchase it?

 

ignore that question. i'm good
