    My CEL came on yesterday on my way home from work. I was mudding on sunday and i got her stuck in a pit. The water/mud was up to my step bar for around 30 min before someone pulled me out. I got it scanned today and i was told my system was running lean. The code is P0171. I did some research and it really could be a number of things. Wondering if anyone was encountered the same problem?

    Some stuff. Not a lot, just some.
    Clean the MAF first and change your air filter.

    Sometimes it's inevitable. Trails have mud holes all the time. :D

    same thing happened to be but vibrations loosened the clip for the maf sensor. I cleaned it and snapped it back in. :cool:

    Yup just playing in the mud, found a pit, didn't realize how deep it was. And in i went:eek: I really hope it wasnt the 02 sensors because i just replaced them and the code is different this time. The guy who did the scan thinks it could be dirty injectors, a vacuum leak, or MAF sensor. Maybe i ripped off a line??

    Disconnect it, remove it, spray it, let it dry.
