I have a stock wrx and i went into a drift in high 1st gear. I hit the rev limiter a few times so i could come out of the drift in first and continue going. Everything went fine with the completion of the drift but the first time i started my car after that drift, the check engine light came on. I believe it might be the timing belt because i have had previous problems with that. The last time the light came on i left it alone for a few days and it was gone. Just wondering if it may be the timing belt or what anyone else thinks and I would greatly appreciate it if someone could give me any suggestions on how to fix the problem.
