Start with the simple stuff; fuel filter would be my first step as engine falters under load but will rev freely when in park = physical constriction or low pump pressure
Plugs do get loose in the block. Had exactly the same experience
It does the same on lpg though.
Mmm, how is the engine earth strap?
Any news here on the Fault?
