okay so ive had my CAI in for awhile now and yesterday i was driving and hit a decent sized pot hole or whatever it was and i got home and thought nothing of it, but then i went out later that night to see my Check Engine Soon light on. So i checked last night my cai came apart where the two tubes meet by the Mass Air, so i put it back together no problem but its still saying the check engine light so idk what the hell to do? any thoughts

 

Disconnect your battery for five minutes, reconnect your battery, start your car and the light should be gone.

 

When the car see's a problem like this it will store the code to let you know something happened. By doing what Zip said, plus I always turn the headlights on to drain any power in there out, it will clear the ECU's memory and it will clear that code.

 

yes i disconnected the battery and it came off thanks guys much appreciated for the info
