It's the last thing you want. You put your jet ski in the water or roll out your ATV and it wont' start. Or it runs poorly, sputtering and dying. Just like that your day is shot. You find something else to do, or spend the day tinkering with it, hoping to get it running.
Too often these problems stem from deferring maintenance, lack of use, or old fuel. These issues lead to clogged up fuel systems and dirty fuel injectors, the most common reasons why your vehicle runs poorly or lacks power.
