Manual-mechanics response on the topic Re: code P0171

If you've already checked the fuel pressure, which should be between 52 PSI and 59 PSI, it's most likely that the MAF sensor isn't working correctly. I'd suggest trying a different one, as it can cause a lean mixture at certain times.

Regards.
