The last few weeks I have noticed that my truck seems to have stumbled with the cruise on but it was always a quick jerk and I was never sure. Today on the way to work I pushed the clutch in coming up to a stop sign and the engine shook and rattled hard enough I thought I lost something from under the truck. It didn't die but I can't really have it down, I live in wisconsin and we have 10" snow coming tomorrow and tomorrow night and since I work for a towing company not going to work isn't an option. Any ideas guys? It's a 2003, 6 speed, with Edge Juice w/Attitude. Thanks all,
Nick

 

Also, I scanned the computer when I got to work and there are no codes present. It had fuel pressure from the lift pump at the time, wasn't watching rail pressure though.

 

water in fuel?? only happen when its cold out?? can you check injectors?

 

I had the same issue on my 2000, ended up being the crank position sensor on my truck, yours, I believe could be the cam position sensor.
