Ward has responded as follows:
Injector faults will always occur if used on gas as the injectors are shut down. It is also unlikely injectors are the issue if same fault occurs on both fuels.Need to determine what type of gas system is being used.Need to measure A/F ratios under load.Intake or exhaust restriction possible.

Thanks Ward
This issue has been a nightmare. The same fault does occur on both fuels. Undid the catalytic convertors from engine pipes and still the same issue(lack of power). I was wondering if the RR is in safe mode because of the door fault. Would and EFI show this up in scan because so far no indication. Is A/F acceleration function? Still no Power. How would gas system be involved, how would I be able to identify this. Any other thoughts? Thanks Kev
