Over the past year my 2005 duel-fuel Toyota Hiace has had intermittent problems. The engine runs very rough and vibrates as if one of the injectors is not working. The engine check light comes on and the car runs roughly for between a few metres and 20 km. When I try to drive to my service bloke the problem rectifies itself before I arrive. I have replaced the injectors and the coils to no avail. Can anyone help?
It's most likely to be an engine sensor, or a wiring connection associated with one, that's the problem. Unfortunately, intermittent problems are hard to detect, because they rarely occur when the mechanic is there to witness it.
