Just buy standard NGK from your motor factors

When you say jumpy do you mean the engine feels like it's moving about? if so check your engine mounts in particular the two front lower torque mounts

I know what you mean mate is not the engine as im running innovative mount and engine is solid but if there,s anything you can think off i will apriciate it and would ignition timming cause this as ill like too check it.
 
Yeah ignition timing is usually the cause, change all consumable parts (basically big service) and report back

Unlikely unless the dizzy was off lately there should be no reason the timing would become altered. Could be bad 02 sensor if it's happening at part throttle.
 
i was thinking of worn cap, plugs etc giving a small misfire almost like a stutter or small judder
just had this exact problem in an accord 1.8 vtec sport

Seems like the distributor coil or ignitor going soon. But choose the cheapest path by changing the plugs first.
