Fault code 27 over 1/2 throttle - Technical Troubleshooting discussion in Forkliftaction's forums

Doosan (& Daewoo) G25E-3:
Fault code 27 over 1/2 throttle

Machine running on gasoline. Engine runs good at an idle, but when revving up it acts like it's in low power mode. Once you get over half throttle the engine cuts spark and dies. After it dies, I get fault code "27". Replaced fuel filter, cap, rotor, plugs, and wires. Also plugged in a new throttle position sensor (foot throttle). No changes and cannot get any dealership help.
Thanks!
