check engine light

[Youngblood]

I was driving my wife to work on Saturday when I noticed the check engine light was on. So I took it down to the dealer and they said as long as it was not blinking then its not a big deal....yeah right this is nearly a brand new car. SO I took it back to them today for a service maybe nothing major is wrong. The only engine mod I have is a CAI and I got that in DEC. If anyone has had this problem let me know.:(

I had the check engine light on before, one of the oxygen sensors was faulty, they replaced it on warranty

The check engine light MAY come on when you have a CAI installed, too much O2 or too little O2 thru the intake. You will need to reset the sensors.

NOPE, and have only heard of getting a CEL when a new intake of ANY kind was first installed but resetting the ECU took care of that.....and have never had any problems at all. I am thinking your problem exists elsewere.
