Well I washed the engine and now I have the engine temp light and the fuel filter light on when I drive it. I made sure to not get the alternator or the air filter with any water on it so thats good. I notice it surges on cold startup or about 2 minutes and then idles normal after.
Thanks for the follow up. I was thinking "great tell the guy to wash it and then he has problems!!" I had a gasket go bad on my aircraft, so today I was out at airport with hose and Oil Eater soaking the engine down thinking of your issues.
