Help!!!
Hello, I have a 99 Ford F-150 4x4 with the Off-Road package. I was recently off-roading with my truck looking for a location to go hunting in Wisconsin. The area was extremely wet anddidn't know the area. Problem is I got the entire truck muddy, engine and everything. While still in the woods the truck started vibrating very badly. I took the truck to AutoZone and had them check for the diagnostic codes and the first time was #8 cyl mis-fire and lean bank 2. I replaced the coil pack on #8 (what a pain). Truck was still running real bad. I have pulled all of the injector and coil connectors and sprayed with electric dry. No luck. Took the truck back to AutoZone and this time showed #8 mis-fire and multiple mis-fire codes 308 and 300. Does anybody know what I should look at more than what I have already? The oil looks fine, so I didn't injest water I don't think. The truck runs great before it is warmed up and runs great above 2000 rpms. Runs real poorly trying to accelerate mildly and when trying to maintain speed. I have just been laid off from my job and need to get this repaired as cheap as possible.
Thanks,

Mark, I agree with 1081, it sounds like one of your wires are off. It's almost sure to be in the ignition system somewhere. If you could, you should get a Haynes shop manual for your truck, they are about $15, and they tell you how to do everything from changing the oil to rebuilding the engine.
