    I have a 1992 512TR and started it up to take it for a spin. The car was stumbling on start up and could smell fuel. It looks like maybe only one bank of the engine is firing and other side maybe not or just a few cylinders. The exhaust on the driver side is warm/hot and the passenger side is colder. I haven't pull the spark plugs out to see what they look like. Any idea what I should look for or where to start? I have the Dave Helms fuse board so not sure if there is something connected with that. I doubt it.
