Other Fuel System Fuel Gauge problem #1

When filling the vehicle with fuel, the fuel gauge does not give a proper reading. Manufacturer serviced the vehicle 6-7 times, but couldn't find the cause of the problem.

Other Fuel System problem #2

While driving, went over bump in road, and truck immediately lost speed. Pressure on gas pedal weakend. There was absolutely no acceleration. I pulled over after almost being hit, and turned vehicle off. Restarted and pull over into autozone to have them hook it up to diagnostic reader. It came back with several codes, that all stated "throttle pedal positioner malfunction" I have bought and replaced this item 4 times since this incident, and the problem still exists. I am forced to drive the vehicle because I have to get back and forth to work, but I'm always very afraid that this part is going to malfunction while in a busy intersection or street, and I along with my kids are going to be killed. It happens at least two to three time a week, sometimes more.
