Yup agree with the top post that's your problem the coil packs just replace it with after market ones like splitfire or yellow jacks. If you leave the problem as it is you'll start to see your engine light will start to turn on if all 3 lights turn on etc you slip, tcs and engine light turn on then I'm 100% sure it's one of your coil packs miss firing. Get some one to scan your ecu to find out which one exactly and just replace it you could probably find one here for $30...or so.
