Default Rough and erratic idling after service

I recently sent my Baleno for routine service.Advisor suggested injector and throttle body cleaning,as car has clocked 47000 kms.Engine was running pretty smooth;but I agreed as he promised improved acceleration and FE.
Later,he called me to take permission for spark plug and air filter change.
When I reached to take car, I was expecting something special.But what a disappointment.I found the engine running rough with erratic idling and excessive vibration.As it was late,I took the vehicle with a promise,that they will look at it next day.
Next morning when I took the car out to drop kids school,it started with abnormally high RPM,which stayed even after a while.So I started to drive with high RPM,but as I pressed clutch to shift, RPM shoot to nearly 1800 and stayed.
Later,in the workshop,they cleaned some part of throttle body,changed some packing and O ring,adjusted spark plug gap(new plugs).They delievered car with warm engine which felt smoother;but next morning,its same story again.

take it to the workshop and catch them by neck, carry the bill also. If its only early morn phenomenon, get the mech to your house to demo or leave the car over at garage overnight.

It can be resolved, they might have to redo the injector cleaning. Check complete engine electrical as well as throttle body plumbing.
