hi
my focus runs fine but when i've been stationary for a couple of minutes the engine begins 'hunting' and doesn't seem to idle like it used to. any suggestions on the diagnosis or the first places to start looking?
Cheers!

 

There's some rubber hoses around the throttle body, check these for splitting/flattening.

Check for air leaks around the inlet manifold/breather hoses.

 

Ok cheers mate
