just got my injen intake and magnaflow cat back and it was fine for a while about 300km and then the famous engine light came on so went back to the preformance shop and checked the code is PO 603 but they can not find anykind of info on that code so they reset it and it was fine for about 100km then came on again now i dont want to take it to the dealer because of the intake will void my warranty any advise on what i should do please let me know oh the car drives great

 

Google is your friend That code is the "keep alive PCM memory" and it will go away after a few ignition cycles. You disconnected the negative terminal on your battery and it is a code telling you that you did just that. Leave it alone and it will go off by itself very shortly, enjoy the sound of the SC buddy

 

thankx for everything

 

I can't wait to get my intake to acompany my exhaust

 

Waiting on my Injen, can't wait.

It pays to have a code reader if you plan on mod/tune your car.

 

Alright so your saying, when you install the CAI you have to unplug your battery and then when everything is installed, you plug it all back in, and after a few engine cycles the light will go away???

 

when you unplug your battery and then plug it back it you will get a check engine light?

 

any autozone will read your codes for free as long as its OBD-II.

 

My K&N intake still hasn't kicked on a CEL...
