is this light because i got headers? or is it because it's due to service? i still have my CEL on because i'm too lazy to put in the anti-fouler, but i will soon.. and this light just came on yesterday.

 

It comes up every 5000 miles.

 

Its just an oil change reminder. Read about it in the manual. You reset it after you change the oil.

 

All you gotta do is make sure your odometer is on the total mileage. Turn your car off. Turn it back on while holding the button in, 5 little lines will be blinking where the mileage is at, wait for all them to go out then it is reset. Easy enough.
