The V8 Owners Forum -

H i not had the car long, starts fine all weathers, when it flips to lpg it starts to go lumpy and stops running unless you rev it then it runs ok, allso it seems to loose power when driving, is this a consumption problem or do you think its a ht lead breakdown the guy had it reguly serviced with an lpg specialist but im not sure about the rest of the engine its a zavoli multi point system, allso where is the lpg filter located on the engine incase this needs changing cheers Rich

By far your best bet is to read this:

Particularly the bit about plugging the gas ECU into your laptop and seeing what's going on.

You could have any number of faults with it, but the gas ECU should give a few clues.

It might even just need calibrating.....
