hi my car seems to be a little unwell at the moment,
car seems to be idling high 900rpm when i put my foot down in park it takes a while to settle back down hangs about at 1300rpm and then drops down to 900rpm and then after 10 seconds it will go down to about 600rpm but runs lumpy at those rpms as if its gonna stall

things ive done throttle body cleaned out,airmass checked,coils n plugs checked,air filter changed.

a friend on mine reckons its got a vacume leak but cant find it,any ideas if my problems could be due to a vac leak.
or maybe some pointers on what else to check and eliminate.

thanks

 

any help with this then guys

 

check the tube from the brake booster
