Hi all, I have a 85 ram 50 with the 2.0L and need some advice on the way it's running. When I start the engine it starts up immediately without hesitation and runs very well but as it warms up it starts too miss a little and run a little rough. I enclosed some pics of the black spots the exhaust is leaving on the floor. Also there is a rotten egg smell that is pretty strong. IMG_0901.jpgIMG_0902.jpgIMG_0901.jpgIMG_0902.jpg
