okay so i took my Honda City 2003 EXi for some CNG tuning today, the car was jerking and had some mileage probs, so got the tuning done and cleaned up the whole Intake Manifold.
Then I found out that the oil had to be replaced, decided to get the car fully serviced.
But then found out that the right side rear wheel was jammed, so went to my trusty mechanic (Munna Bhai), and got a check-up, found out that the hand brake cable was faulty, went to plaza and got a new japanese one for Rs.1400, went back to Munna Bhai and got the cable replaced, for free 
All took 9.5 hours, phew! now the car is running great MashAllah!
