When I finished up I had misfires in three cylinders. Couldn't figure out why but took them back apart and made sure everything was good, saw nothing out of the ordinary but when reinstalling the coils, I ensured the harness clicked into place. Everything was good after that.

Car ran rich for a small period of time and cleared up and I don't have the hesitation/miss up top like I did before. Now I have the itch for more power
Nice work, the first time i did my spark plug change i got the same issue, really need to ensure they all seat well.
