No serviceable fuel filter to change.
Try replacing the Throttle Position Sensor and keep yours for a spare; they go bad from time to time and won't necessarily trip a check engine light.
They are a really important sensor in that they dictate both fuel and timing.

If you do replace it, disconnect BOTH battery cables from the battery and touch the cables briefly together so the ECU can't retain any information from the old TP sensor in memory.
The truck MAY idle a touch rough for a few seconds until the ECU figures out what planet it's on after touching the cables together as it will be starting from scratch gathering info from the sensors.

PS Touching the cables together is NOT the same as disconnecting the battery and/or all three ECU cables, standing on one foot while doing so with a stopwatch, etc, etc.
It works.

Good Luck.
