Toyota 7FGU30:
No throttle response, engine light flashes 2 times? 4Y ECS LPG

Unit starts and runs fine, but intermittently we have no throttle (will not come off an idle) and the engine light flashes what I believe to be a 2 code. Any insight would be appreciated.

Check harness plug at the electronic throttle connector. If higher hour machine, wiring breaks at the angle of the connector. Another issue if I'm wet/dirty environment is the cpu box below the left step. Water can back up into CPU box and corrode the connectors attached to the distribution panel located below the cpu
