running megasquirt efi.
once the engine is at operating temp and ambient air is over 80 F.
randomly it seems the engine will drop rpm or stutter. just like bogging it down with too much fuel.
for the most part it doesn't seem to only be at idle as I have had it happen while moving too.
it doesn't kill it off and if it does die( cause it does sometimes putting it into gear) it fires right back up again.
watched it on the megasquirt software and don't see any signal drops and I can track both fuel and spark when it happens.
it doesn't happen when it is cold outside, or when the engine is just warming up.

was talking to fastman efi and he said to drop the pcv. because it is a giant air leak.
figured I would give that a try and put on a breather.
if that doesn't solve it, I pretty much am going to drop the coin to get a supported system so I don't have to do the tech support myself.
