Gday,
I have a vn 3.8v6 ute and it has developed a real bad miss,it cant be driven.but will idle fine until it gets a load put o it
I have replaced plugs,leads,coils,dfi module, crank angle sensor and the fuel filter.Nothing has made a difference.
Anybody got any ideas?
Thanks
Kane
It does sound like an ignition miss. Maybe go back over the leads, plugs, coil(s), DFI. It's easy to crack a s'plug. Often you can see arcing on the ends - inside the insulating caps - of the 'lead on a cylinder that is missing. Maybe an injector? If it idles OK, it's probably not a mechanical fault i.e. vac. leak or low compression.
I got it going again,turned out to be the fuel pump not pumping a high enough volume into the motor.
Thanks for your help
Just a note for anyone else who finds this in a search, I had an identical problem some time ago that was caused by a bent fuel pressure regulator. Fine on idle, and free rev'ing, but unable to cope with any load.
