Well i spoke to the mechanic and he said he would run it on his comp and charge me £35 to clear and read the codes not bad i guess. He recons the problem I'm getting is from the throttle housing he said to clean the back end of the housing i only cleaned the bit i could see like in front of the butterfly think i might take it right off and give it a clean. But he also mentioned about resetting the (kams) or something to do with the idling speeds he think the idling speeds might be wrong. well i clean the throttle out on the weekend and if get no luck its going to be sent of to get fixed cause its costing way to much thanks for the input anyways guys will let you know what happens
