The idle is weird. It only idles funny when in park or neutral and that is not always happening. When I shift into drive or reverse it runs fine. Sometimes it runs perfectly fine and then other times it stalls completely when I shift it.
The intake manifold gasket has not been replaced yet. I am thinking that is what I am going to attempt next. Is there a place to find step by step instructions. I am a helicopter mechanic so the only engine I have worked on in depth is turbine engines.
