Did you replace the cap and rotor recently?
OK, try the cap and rotor. I have seen MANY where that alone was the issue and if you have not changed it any time recently, it may be due or overdue. It may even be why it was turning slow if the spark was going down the wrong line.
It is very simple, pull the wires off the cap, remove the 2 torx screws and remove the cap, then remove the 2 screws for the rotor and remove. The cylinder numbers are cast into the cap so you can easily line them up. Just be sure to make sure the screws are not over tightened.
