Anybody with CAI, Y-pipe, and RT Cat combo that has no problems whatsoever with SEL problem? Cali emission or Fed Emission cars!!

Thanks

 

I have the same setup on my car. Hybrid Pr tube Cai w/jwt, Y-pipe, Full cat-back w/muffler & RT Cat. I'm Cali emission. No SEL here.. When did you start getting it? Have you ran a scanner on it yet to pull the code?

 

yea i got a CAI, Y-Pipe, and RT Cat and i got no check engine lights at all ever...

i got cali spec too...


u gotta check the sensors maybe they put them in wrong or something... check all the hoses by the CAI aswell... make sure everything is nice and tight and not loose or off...

 

After a mod like this, should always reset the ECU. Keep the negative cable off overnight.

Really..gosh..i have been having the problem for 2 months now. Tried all of the trick above..the SEL will return in less than 2 weeks. Error code is P0420, catalyst inefficiency bank 1.

Did this happen after you put on any one of those mods?

 

It happened after I put on my CAI, I had Y-Pipe and RT Cat for about 4-5 months prior to CAI install, so it's big possibility that it's the CAI, but WHY??????
