Duff coil would be first idea.

Any fault codes in ECU?

Got access to a live data scanner ? Can see what's properly going on then, will cost about £40 to get someone to do it if not

Disconnect battery for a few hours best overnight then reconnect both terminals. Then turn on the ignition, don't start the engine though and don't touch the pedals. Leave on for 30 seconds then turn ignition off and then start the car straight away not touching any pedals. That should align the throttle body.

I will try that tonite dude n see wot happens, iv changed the plugs,dizi cap,rotor arm,coil,maf,relay 167,relay30,leads n fuel filter, if I remember right the throttle body was clean last time I looked but will check again.
any body around the bude area got the full diagnostic iv only half of it
thanks dave
