My vehicle started hesitating and seemed like it was going to stall. I changed the coils and plugs. Still acting the same. It is firing better and occasionally actually runs quite normal. Not often though.

We need to run the codes first to see what's going on, also I would check the engine for vacuum leak by following these guides, please check the engine when it is cold only.

You could have low fuel pressure which is causing it. The pressure should be 330 - 380 kPa (3.4 - 3.9 kgf/sq.cm, 48 - 55 psi). Please check the images below on how to test the fuel pressure and change out the fuel pump.

Check out the images (below). Please let us know what happens.
