Answer 1

If its a clacking sound, its a valve lifter. This won't effect your power yet, but it will eventually get worse and in extreme cases prevent the valves from operating. Put some additive in your oil to help it out.

Answer 2

it could be the fuel you are using try using a high octain fuel in it. i had the same problem in my chevy trk & it fixed it.
