The CalMini filter should not cause a CE light. I would double check that you don't have any leaks between the mass air flow sensor (the thing you attached to the blue CalMini bracket) and the throttle body. If all looks good, pull the ECM fuse in the fuse box in the engine compartment for about 30 seconds and reinstall. This should clear the light. Then wait and see if the light comes back on.

Or take it to Autozone and pull the code.
