Fuel efficiency drop
fuel efficiency droped compare to my friend's car, would it be the spark plug?
When i put my car (4AT) to D, i can feel a bit of vibration and sound from the mounting? or something else, is this related?

"Could be driving habits. More stop and go or short trips will do it." Razz1 you might be right also because i live in city, he lives in rural area.

Could be you need the latest flash.. could be a fouled air-flow sensor.
Both are easily remedied..
But I agree that the driving habits has a great deal to so with it. I can't help driving it like I stole it everywhere I go. I love to gun it off the light and hit the speed limit in as short a time as possible. I like to hit the redline. I love to feel the power band from 4K to 8K RPM... I'm lucky to get 17MPG.
I know.. I need to "grow up" and cut it out. But it's just so much fun.

plugs, replace plugs...
cat, replace cat with something hi flow.. no cleaning it.
broken motor mount... would be my bet for vibration... see if you can find a product called b&g 44k. it is an engine / plug / valve / injector / carbon cleaner... it is about 20 bucks in the us for a can, but the stuff works...
