Found this pic on Club Polo that shows my engine bay perfectly.
Ive removed the throttle body and cleaned her up, but im now led to believe that my car is actually an injected car??
anyways, cleaned the throttle body, and now she revs at 1800rpm at idle.
Apparently it needs resetting at a garage now? And trust it to be late on a Saturday that I get this all done, when the garages are all shut.
