sounds like a vacuum leak to me too, when elbow at the inlet manifold if split will allow unmetered air into the inlet manifold causing the symptoms you are experiencing...it is unlikely you will be able to remove this elbow without damaging the retaining clip...
when mine went last i pulled the elbow and clip and replaced the clip with a tight cable tie..a good tip is to heat the elbow in water to let it expand...the pipe runs behind the inlet manifold so it may be easier to run a length of 4mm samco under the fuel rail....like this

or you may want to remove the inlet manifold like this...

cheers
