code 43 fuel delivery system.symptoms
im going to break down the padal travel into percents but its not to scale (for my problem)
i was also thinking Throttle Position Switch, but what made me stir away from that thought was that when its in idle it drops to low idle speeds and jumps up to 1,300..
the low idle does not happen all the time.
- when i press my gas pedal about 25% down for a regular take off it works fine.
- when i go down to 50% and 75% it starts to act as if i let go the gas pedal.
- when i go 100%, pedal to the metal, it works fine.

- my fuel pump does prime for 3 seconds when in the on position. right before engine cranking.
