1997 Explorer P171 and P174 codes Thanks for help
A couple of months ago I posted that I was getting P171 and 174 lean on
bank 1 and 2 fault codes. Some of you suggested cleaning or replacing
the MAF sensor if nothing else obvious was wrong. Cleaning it using
CRC Lectramotive cleaner did the trick. Runs fine and codes are gone.
Thanks all for the advice. Saved me $150 for diagnosis and $250 for the
part.
