My 5.7 liter volvo duo prop all of the sudden has started to idle high. It doesnt do it all the time. And when it does do it if i turn the key off and on real fast it then idles normal. Or if i shut the boat off and re start it the n the idle goes back to normal. But as soon as I pull the tubes or drive around for a minute and go back to neutral the idle go back up.
So, what should i check, I am leaning to a sensor. Air sensor maybe ?
