I got a check engine light last night after a 1/4 mile run. It was after my run was over and I was slowing down to get off of the track. I left the car in 4th gear to help slow down, and the light came on at about 4k rpm. I unplugged the battery and bled all of the voltage out of the system to clear the code. The exact same thing happened two runs later. Anyone know what is causing this? I dont think it is the code for my cats b/c it usually take a while to trip the MIL for that. Plus I have MIL's emininators and they havent been acting up in a while. Thanks in advance.
