Hey guys, i just got a CAI and the Pully kit from RRM, they also installed it so i'm sure it was done perfectly. but my check engine light comes on after about a day (60miles) after i reset the computer. i did about a 20min idle after resetting the computer last time. i'm going to check the code at work tomarrow, but is it bad to drive with the light on if the car is running perfect?? i havn't had the car run better!

 

It's fine to leave the light on. Mine's on most of the time.

 

thanks otter, thats what i thought, i've even thought about just disconnecting it, i feel like if i look at my car wrong the light pops on!!

 

Thought about doing the same with my girlfriend

 

i always heard that a car runs in a safe mode when the light is on. that it runs rich or something. so if i run without a cat the light wont make a difference?

 

i hope it runs a little richer !!! i'm getting a lean code, so it would balance things out!

 

The Lean Code Came on because of Your CAI. It's been a debate whether it's good for the car since a tune is needed after most CAI install. A good Drop in Filter is the other way to go about it... sorry went off topic a bit but still useful info...

 

Not an Evo.

 

wait... My CEL goes off? haha jk
Yea I have a faulty heater core on my upstream O2 sensor, has been dead for over 8 months and the car runs fine...

 

I think you're thinking of limp mode, and you would deff know if you were in it since the engine loses all its power and cant rev past 3k...

 

i just took my gel cap for my CEL out i know if i got a problem and i check it often same with my SRS light cause i no loget have the stock seatblets in i just have racing ones there, but that light can only be shut off by them.

 

My cel is always on at least until dan turns it off for me.
But....it comes back on anyway.

 

when i put my cai on, the cel was only on for 35 min

 

I have the same the problem its from CAI, the only thing is, is not good on your car if you listen to your car run at a low idle take off you can hear it ping in the motor, the minute i take mine off the ping is gone, i guess you could say its more of a spark knock,

 

Same problem with mine.
