It sounds like maybe a vacuum leak, timing issue, or crossed plug wires.

I use a can of carburetor and choke cleaner to check for vacuum leaks normally.

i do have one question? could the spark plug wire be bad even if it look new?

Yes it can. The O2 sensor can, if malfunctioning badly enough, it can cause the computer to hold the injectors open longer than necessary, causing an extremely rich condition which can cause a rough idle.
Check to see if it's throwing any codes,whether hard or soft.
