First off, thank you for responding to my situation. This machine is only 2 years old and Im pretty sure they bought it new. In answer to your question: there are no fault codes flashing. No check engine light either. And yes, it will display the fault codes if you depress the gas pedal 3 times. It will also clear the fault code memory if you can press it 10 times in 5 seconds but you got to be quick. I have stripped and rebuilt the LP system from the tank to the throttle body without any change. I have even tried 3 different LP tanks in case something was wrong with them.
