HELP Strange 100hp gain??

I posted earlier I was considering upgrading gears because my YJ was a dog on hills. Strange thing happened on the way to work this am. While in 2nd gear my jeep bogged down for a split second..then all of a sudden it took I had a extra power boost. Every mountain I went over and incline... I cruised up with at ease in 4th gear. It was like something released. Has anyone ever experienced this?? What was causing it to run like crap before this? Could there have been a vapor lock or something?? I'm puzzled! I love the way it is running now, and don't need a gear upgrade.

I think your cat is bad and was clogging up your exhaust system. And somehow it moved and cleared itself. Did you hear a rattle under you jeep before?

I didn't!! It ran GREAT on my home yesterday. Do you think it could have been a injector clogged?? I just hope it does not come back!
