P0172 - Excessively rich condition..
This one says to check the O2 sensor for proper installation, MAF sensor for blockage, vacuum hoses for splits/kinks, dirty filter, throttle body blockage. If that's all good.. then says to inspect evap control system, FPR, injectors..

thanks to iceman for this explanation i found in a previous post.
