If I go out and restart it before the engine completely cools down, it will idle way too high. Seems to be heat related. I replaced much of the cooling system last year (head and lower gaskets, radiator, water pump) as it ran hot. That problem solved now this high rpm. Perhaps it's a vacuum leak? I might have put the hoses back on wrong after disassembly. Any ideas? Hose diagram or photo of another 3.4 might help? Thanks!
