I would recommend you to go Honda Classic 3s I-10/3 for complete tuneup and full checkup according to odometer readings. They are best in tuning. In Islamabad, no one is better in tuning (tappet adjustment, throttle body cleaning and other stuff) and other works. Meet with workshop manager and tell him all story. He will help you
So don't go to any roadside mechanic, they will ruin your car. Now choice is yous.
