Do you have a scanner to check the APPS (accelerator pedal position sensor) output? Does the LPG system use the O2 sensors for fine trimming?
Hi thanks for your reply, I bought the car back in December and it's been back to the garage many times now, it does run the same on petrol as for the rest I wouldn't know but I will pass this on to them, I don't think they have a clue either, I thought it might be something to do with the multi piston displacement sensors but not sure, I had a 4.7Ho overland before for 8 years wish I kept that now.
