I had it in a really high gear as in pedaling really fast and it was constantly skipping. When I shifted to a lower gear it was going better, but if I really mashed down 90 percent of the time it would skip until I let off of it.

Im gunna look at the rear derailer tomorrow make sure it’s still straight, but i have no clue how it would have gotten so badly out of whack with my just cleaning the chain, and cassette.
