One more thing about SeaFoam. Don't over do it. More isn't better. The directions say one ounce per gallon. Stick to that. It will cause your engine to put out white smoke if you over do it.

Also, if you are having idling problems try some premium gas with the SeaFoam. I usually use mid-grade, never just regular and I occasionally will fill up with premium. All of my engines idle very smooth.
