My 4.5l petrol patrol has lost lots of grunt. has new spark plugs, leads, cap, coil and rotor. Nissan tested it and cant find any fault with it. Any recomendations. Or may be some one on the southside of brisbane that knows there stuff.

if your got a carb then you might be lookin for awhile good carb shops are few and far between,

Check your Catalytic convertor out. Some times they crumble inside and block the flow and will cause poor performance.
