Engine code from obdII P0121 reading Pedal position sensor A ckt range/perf 10/31/09.1st time p0123 pedal position sensor A ckt high input 09/01/09. I replace the tps in september and the fuel pump. NAPA will warranty the TPS if it is the issue. My truck is hesitating at 2000 2500 RPM's irregularlly, inconsistently and has even stalled as I am coming to a stop. Air filter is clean. Oil recently changed, injector cleaner used with no improvement.
