My f250 last week started running funny after some really cold temps. It won't run full throttle, maybe half the rpms it should have and when it does it doesn't have much speed. After about 35 mph it starts shaking pretty bad. Any ideas on the possible problems? Trying to avoid taking this to the mechanic but it is looking inevitable. Put some deicing stuff in there and ran it for awhile but that didn't seem to help much. My first thought was that I had some water in the fuel due to freezing.
