So recently I was driving my rsx with no issues. Then I started to realize that when switching gears, the car would lose power. So I would start off at first & you could push the car as much as you want but it would only slowly accelerate no matter how high you rev it. Same goes in every other gear as well. I can barely pass 25 mph. No lights came on so I’m not sure what the issue is. Also smell something burning but I can’t tell where it’s coming from.

 

First thought: roasted clutch.
Second thought: plugged cat.
