i do change my spark plug december,and i don\'t drive it like daily car,every sunday drive once a time!

Maybe it needs more than just a Sunday drive? take it out and give it a jolly good thrashing but i do agree with spark plugs or even leads. Are you running a standard ECU or aftermarket, if standard you may be able to pull some codes of it if its an electrical fault.
