I've had a look in my Haynes manual (for the 1.8l and 2.0l models) that this is "self-adjusting".

Does this mean that I should never have to tighten it up? I only ask as when I cleaned the throttle body some time ago it's always seemed slacker or not as responsive since.

I think I may have stretched the cable, however if it is "self adjusting" as the manual states for the other models, then this would not make sense?

Thanks, Alex
