Wrenching is a term that means working (mechanically) on your bike.

It's possible that your chain is worn. If it is, you'll need a new chain, and likely a cassette. After you cleaned it, you re-lubricated it, right? Gasoline and diesel (and many other solvents) dissolve oil. So if you cleaned it and didn't lube it afterwards, you have accelerated chain wear. This happens because if there isn't a protective layer of lubricant on the moving parts, they will wear directly on eachother.
