It could be alot of things. If it hasn't had a fuel filter lately I would start there. I also would change the FRONT O2 sensor if the truck has more than about 60k miles. O2s do wear out.

It runs pretty good, maybe missing a little.

It ended up meaning a new Mass Airflow Sensor in my 1999. I don't know what else the mechanics check for the cause of P0171.

I think he was thinking you had a K&N filter and the oil from that got all over your Mass Airflow Sensor and caused it to fail. If your using a Regular Paper Filter then that wasn't the reason.

Too bad dealers don't clean things instead of replace them. (We're not all mechanically inclined.)
