I mentioned earlier it was having trouble shifting, well now I'm having slight vibrations. The truck doesn't sound the same, goin down the free way I press on the gas and it's almost like it has to work harder to get goin. I just replaced the spark plugs last weekend with auto lite OEM recommended plugs

 

you shouldnt of used those junk plugs. thats probably your problem. go back with motorcraft

 

Went to autozone and had them hook up the scanner, so cylinder 2 is dead. I'm gonna try switching the coils with cylinder 1 and see if cylinder 1 goes dead
