If its the original fuel used then this may have degraded.

1. Check or replace filters.

2. Injection on idle carbs could be narrowed from lack of use.

3. Blocked air filter.

4. If auto fuel inject blockage or fueltank pump power faulty.

5. Choke usage not fully used so still running on a cold engine.

6. Auto choke could have a damaged diaphragm.

Hope these help :rolleyes: . but could you reply stating type of engine 3.5 3.9efi or above and age of vehicle. :huh::blink::unsure:

regards fellow v8 fuel burner :D :D :D :D :D

thanks for the replys, found the problem, after changing loads of stuff on the truck, it turned out to be 1 of the fuel pump wires bin choped/snaped in half, and was touching on the chassis to earth, and when going over bump not touching earth and then playing up.
