my check light lit the other day, and i just had autozone use the scan tool. the code that came up was "P0441 - The PCM has determined that the purge flow in the evaporative emission control system is incorrect for the current engine operating conditions."

what does this mean, in layman's terms? is this something that just effects my emissions, or the beginning of a serious engine problem? basically, can i still autox in the morning?

thanks for your help,
phil
