Sounds electrical under the hood any ideas how to chec and replace parts. i noticed at high rpm around 5,000 it goes up and down,even at idle it has a miss.
Mine stutters and stammers alot if there is a little water in the gas. Try cleaning out the tank, fresh gas, and add some gas drier. It may not fix it, but its cheap and easy and will eliminate a possible cause.<br /><br />A repair manual has a troubleshooting section for testing the ignition system.
