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.
have the same problem?
