cel comes on in 2nd/3rd/4th gears when i rev past 8500. when i shift, it goes away but comes back as soon as a reach 8500 or past. once the car is turned off and i try to check the code, it shows nothing to be wrong. any ideas? the car runs great! could it be hondata related as i run a s100/p28. oil pressure is fine too. this is an allmotor setup.
