[7th Gear]

I recently installed a weapon r secret weapon intake on my qc (2.2) Started it up no engine light. went down the road no light. came home parked it. left later and a mile or so down the road the light came on. went over to a friends and unhooked my batter for about 10 minutes. started it up came back home with no light. next day went off to work and the light came back on. what is there to do to get rid of the check engine light? anyone else have this issue?
