finally got my code 43 sorted yay!!! replaced the throttle body as my old one was sticking anyway and well the code has gone.....so lets hope thats an end to that but now i got code 42 idle control valve so ive adjusted that to make it idle around the 800rpm mark reset the ecu and its now a waiting game weather it comes back and if so ill av to take it to bits n clean it out i guess and if all else fails its a case of replacing it?
