98 TJ having some trouble

So my jeep has been running sluggish lately. All this started to happen right after my last oil change with sea foam and added sea foam to the gas. It also would not rev past 4000rpm. Sounded as if it was hitting the rev limiter. After disconnecting and reconnecting one spark plug, and a fresh full up of 100% gas, it's running fine. Any suggestions?

Care to elaborate. What's wrong with it or why is sea foam causing it to act up?

I personally hate it. My dad owns s machine shop and we get quite a few seafoamed engines in.
You have to really flush it out when you use it.
Lucas or stabil is better.
If you need to flush the oil then a little diesel fuel works great
The 4000 rpm issue was the sea foam still in the system
