Engine Performance problem
2002 Mercedes Benz Sprinter 4 cyl Two Wheel Drive Manual 80000 miles

It is a petrol lpg, it will not rev over 4,000 when driving along, it can be okay one minute and then next misfires and runs as if running on 3 cylinders, lack of power.

Have changed spark plugs, ht leads, coil packs, throttle body, air flow sensor, changed air box sensor. It cannot possibly be the injectors because when it misfires I have switched it over to petrol and it seems worse, injectors would only cause problems on the lpg side.

Hi. I have exactly the same sprinter, lpg petrol 2002 and recently mine has been doing the same. Ive started down the same route as you have but still no joy. Did you manage to find out what the problem was. If at all you cured it I would be very grateful for the advise.
