Truck starts but dosen't stay running. The idle goes up and down, then dies.

What is your question?

We have changed the spark plugs, wires TPS, distubutor cap fuel filter and rotor. We checked the onboard codes and it said the TPS was bad, but we have put a new TPS in and it still does the same thing. We can't even drive the vehicle due to this problem.
