cheers for the suggestions guys,thought it might be the throttle flap at first but is shut fully also the tps but this seems fine,think i have the ofac stuff bought it off ebay the ecu has the ofac barcode sticker on it,and the map sensor is different from the old xr one its like a kind of offshaped rectangle one side comes down at a slight angle and the other is straight anyone got a pic of ofac map so i can confirm this lol,will need to check again for any air leaks around the inlet manifold as had a look as thought this was a possibility cant really run it to locate the leak though
can this icsv jam open then mate how do i check it is working properly,am i right in assuming that it cant be something electrical causing the car to do this,it has to be drawing air from somewhere either from a good old fashioned leak that is letting air bypass the throttle butterfly,or a faulty component like icsv letting air bypass throttle butterfly
