Ok I have searched all over the net and can't find a good solution. I put a Badmab header and zzp 2.5 catted dp on and now have a code 1133. The o2 's are 6 months onls and denso's not the cheaper ones. Anyway has anyone gotten rid of this code after a header and or dp install?.

 

IT's saying your O2 isn't working when the car is warmed up and it's taking too long to work basically.

 

I get what the code is, just curious if anyone has had same code after header install

 

Never got that code from messing with the header or exhaust. Like I mentioned to you, the Denso O2's are known for acting up in these cars. I'd pull it and inspect it, and or replace it with a factory NTK replacement.

Knowing Badmab and the cheap quality it is possible the O2 sensor bung was welded incorrectly causing the O2 to sit back to far causing false readings.

 

That is kinda what I am thinking, I ddnt have the code prior so I am leaning that way. I guess I just need to get the stock manifold ported and call it good

 

That's a better option anyways and will flow more than the badmab.

 

Italian joe has one for sale I think, he does a very good job
