Try running some SeaFoam in the fuel tank, it could be dirty injectors.

Worth a try it is fast and cheap.

Tried for a tank of gas did not correct or improve rough idle issue

Since it only misses at idle and runs great above 1000 rpm I decided it must be a vacuum leak. Checked all hoses and pcv valve. They were all ok. Decided the intake manifold gaskets must be leaking. Pulled the upper and lower intake manifolds and replaced rubber gaskets. This resolved the issue. It idles and runs like a new car!

Glad you found the problem, it seems odd that it didn't set a lean code for unmetered air, but stranger things have happened.
