How many miles on the truck, what octane gas are you using, what brand of plugs and wires did you install?
Send me your number and I'll walk you thru this.
In the mean time, if your cats are shot, stop driving it before you rack up a bigger expense.

 

jesus christ dude, that isn't remotely correct diagnosis. Geez walk away and let a professional do it. Oxygen sensors geez, misfire on number six starts with a plug and wire and you add coolant dye to see if the misfire comes back. if it does then check for coolant dye on number six cylinder plug. if its on it then it haves a slipping liner.
