Might still be a problem with the LIM. Morning hesitation can be from seepage into a cylinder and it has to clear itself out before it runs right again. We had a similar problem with a grand am that had a bad LIM and it would cause a #6 misfire on occasion. Ended up eating a cam bearing and snapped the cam in half as well as gummed up the #6 rings when I tore it apart.

I'd do a leak down test and a coolant pressure test on it before I did much more driving with it.
A temporary fix does not exist. It becomes a solution until it needs to be fixed again.

Well... If it's disappearing, and you're not seeing both leaking somewhere, the only other option is... It's burning both.
