button?

actually, this always happened. it happened from the time i bought the car new. it was just that it would happen once, then it wouldn't happen again for several months. that's why the dealer could never find the problem. it's just now that it's happening a lot more often so it's becoming annoying.

the cap and rotor have been replaced. the spark plugs was changed about 2k miles ago... we dismantled everything and checked for burnt spots, misfires.. it's all fine.
