And on a worse note, I went to clean my engine to day, and I have tried, every thing imaginable, to clean it, and with out scrubbing for hours, it will not work, and one have any suggestions? :help

get greased lightning.. cover up your intake with a plastic bag.. hose down your engine then spray it down with greased lightning and scrub.. then hose the engine back down and blow it all off with a lawn blower or somthing like that (u want to get ALL the water u can out from the engine bay) then take the plastic bag off and start your car.. if u did it right it will start right up.. if it doesnt start wait a few hours and try agine.
