Serious problems after wheeling PLZ HELP
So I went mudding last night went through a puddle just a bit to deep I think? So now my truck is running like crap, just vefore I went out I changed my oil with mobil 1syn and a motorcraft filter. Its seems to be idling high around 1200-1500rmp but only a little bit. The worst part of it is from around idel to about 2100rpm its really rough jumpy sort of the its gone or u just cant feel it. I replaced the air filter this morning, still no luck. The other serious problem is that the temp gage, which uded to chill around half goes up to the line and the check gage light comes on and off. I've driven about another 100 miles today with it like this doesnt really seem to be getting that hot actually, I have check the oil about 5 times and its fine no water or anything.
Any help we be GREATLY appreciated.
