Hey guys. Hopped in my car today after driving around town. Go to start it and it fires right up, But...Idles like an out of balance washing machine also it smelled SUPER rich with some smoke. Got on the gas to clear it out but once it settled down still idled like crap. I shurt it off and refired it. Same problem but not as bad. Shut it off again and fire it, Then it runs normal. What could have caused that? thanks guys.
