No damage required.)  Look at the bulb on one side of it (it looks like a drop of old brown school glue.)  Get UR favorite rubbing alcohol and a Q-Tip.  Carefully (CAREFULLY!!!) clean it all around, then when it drys a bit, reinstall and reconnect.  Don't forget to reconnect it.  After 33,5K miles mine was rather dirty though I didn't notice it when I installed the CAI. Hope that solves your problem as it seems to have solved mine. _____________________________ "There is no tool you can buy that will replace experience." - Josh Mills, C.K.DeLuxe (in reply to WarDogsOfNam) Post #: 2

I had just goten some gas and within a few miles it came on. I just checked the cap and it was not tight so i tightened it up . The light is still on so how can I make it go off  ? Do u think this is the cause ? Should i drive the car ? (in reply to WarDogsOfNam) Post #: 4

However, that said, also try what SPeeDy suggests, only leave it off for at least 10 mins after draining as much juice out of the system as you can.  i.e. depressing the brake pedal several times.  A few seconds won't do it.  As I understand it, the ECU has capacitors in it (like all electronics)  that need to be fully discharged to reset itself, so the longer the better. _____________________________ "There is no tool you can buy that will replace experience." - Josh Mills, C.K.DeLuxe (in reply to SPeeDy3) Post #: 7
