Check engine light came on while the car was idling, indicated a misfire in cylinders 1 and 2. I can't feel/hear/notice anything out of the ordinary from idle to 8100 rpm. Drove about 150 hard miles at Texas World Speedway w/out a single hiccup, yet the light still remains. Reset the ECU, and the light came on after a few minutes of idling. I haven't had a chance to pull the plugs and inspect them but I'll be doing that once time allows.

Recently replaced plugs/wires/rotor/cap. Basically stock Integra GS-R.

Any idears? Thanks.
