i had a real bad kickback feeling when the engine was put under a bit of stress on the road,
well today i went
-oil filter/oil
-fuel filter
-air filter
-plugs
-leads
-full throttle body clean OFF the car
everythings sweet as now
it ended up being the plug leads so to Hudson and JTop i think, thanks guys 
when doing the plugs i didnt buy leads, and changed the three drivers side, then the rear plug on passenger (6) replaced but the lead wouldnt go back on properly pulled it off again and the connection fell on the ground, so im pretty sure cylinder 6 hasnt been doin much lately, VERY VERY happy now as on off thing, is carbon deposits on the plugs a bad thing? how much is bad?
everythings sweet now, and for anyone experiencing simply shitty driving, pickup, accel, anything to do with throttle response, id definitely look art removing the throttle body and getting some Throttle body/Carby cleaner and give it a good clean, the mighty paj runs HEAPS better now, nuthing too serious, about 10 mins of work for an excellent result!
