Got back in it to go back to work and its back to running on 4 or 5 cylinders. At a stop light it shakes and stutters like its got a huge cam in it. While acclerating it feels like I have one square tire. And when I back off the throttle is runs smooth.

When I got back here to work, I put it in Park and walked around the truck. It was stuttering and sounded pretty bad, like it was going to stall. But the smell of rotten eggs was most noticable.

Anyone have any ideas? My SES light came on on the way back, so I will attempt to get the truck to Autozone tonight and get the codes read. Anybody have this happen?
