No throttle contol

Hey Everyone,

i have a doosan that I would love to set fire to. been going around in circles on this one its coming up with code 471, etc diver open checked the wiring all good checked the tps ok as well the etc to ecm wiring all good. so bought a new throttle body installed it and same freaking thing.

morel of the story is i have no throttle control but it idles fine. open the throttle even a bit and you can hear the truck bogging out, best guess its leaning out but not sure why. also hold it wide open and it just dies.

so any ideas much appreciated, in the mean time ill grab the gas and a lighter.

Same symptoms, found a plugged vapor line.
Also could be:
- Fuel supply
- Regulator problem
- Vacuum leak, PCV valve, confirm all hoses are ok
- Spark plugs.
