Uhm, it has a 'hard code'. If it is under warranty - take it back to the dealership. If it is not covered - have any reputable shop pull the codes and make a recommendation.

Remeber - emmsions equipment warrantly extends WAY past the everything else warranty...

well the check engine light indicates a problem....you have to fix the problem before resetting the ecu, or the CEL will keep coming back

its the 2.0...i have tightened all clamps 3 different times...i have no idea where it could be leaking but if you could give me some clue as to where it is most prone to leak that would be great...thanks

actually usually the prob is with the 1.6....try using some alcohol and a q tip and cleaning the MAF...sometimes it gets dirty especially when changing to a CAI...then when resetting the ECU,disc the battery, step on the brake and reconnect the battery

1.I would suggest removing..the cai..and resetting the ecu..and see if you get a cel!

2. If step1 removes cel reinstall the cai

3. if you have done step 1 & step 2 and there is still a cel..Sell the POS..and stay stock..LOL..j/king

Make sure that you have checked everything..especailly that the IAT is correctly plugged in and connect..and that the maf is connected..

ALSO BE SURE TO CHECK THE THE MAF IS POINTING THE RIGHT WAY..THERE SHOULD BE A SMALL ARROW..THAT ARROW..IS THE FLOW OF AIR!

Make sure you check up near the brake master cylinder and towards the block that all the sensors and things are all plugged in...one time when i was switching my intake i realized that one of these things was unplugged by accident even tho i didn't unplug it.
