Hi there, I have a P38 with a Bedini LPG system fitted, I have started getting "Gearbox Fault" on the display but it only comes up 20 seconds after clicking onto LPG. It is also running abit rough on petrol at moment and rather under power. It is changing up and down the box ok when on petrol but "clonks" into gear on LPG when the fault is showing. I had it plugged into a computer last week and i was advised to change the alternator and one of the lambda sensors also to fit an engine and gearbox earth which i have done but it is still the same. Could anyone help me out?
P/S I was told the air flow meter is working correctly. Dave.
