Yesterday my engine check light was blinking and did a engine scan to find out 4th cylinder was not firing.When the plugs were checked 4th plug was not even removed for the matter cleaned during the previous tune up.Which was done in a garage down syvester road Mount lavinia who is a real cheater Without doing a proper job he sent me to Nilwala motors to repair the gear box.The crook wasted my time and mobey. After cleaning the plugs and tune up car is completely fine.
