pressure washed motor/undercarriage, now misfiring p1300,p0308,p0306...
I've already searched and come up with misfiring cylinder 6, 8, that can be resolved by tuneup.
My question is can I just change the cylinder 6 and 8 plugs and wires only, or do I have to do all of them? Also can I just pull the spark plugs and clean them off and see if that works?
I've never actually pulled spark plugs but from what it looks like I just take a wrench and unscrew them like the O2 sensors... easy enough right? And they should be simple remove and replace with no adjusting or anything?

You most likely will be OK when it is dried out. But that might point to insulation on plug wires that is breaking down, and it will get worse, could also have a split in a plug wire boot, or even a cracked coil. Once it is purring again try looking under there in total darkness to see if you can spot little arcs.

If you drive for 1/2 an hour - all the wires will dry out.
Clear the codes.
if the codes then come back - then you have problems..
I really cleaned my engine compartment and did not have any codea at all with a pressure washer.
but, I have new wires on the truck with new boots and all that.
Hummmm.
You may yes need new wires.

If you've never replaced spark plugs, replacing the plug wires (two or all eight) may seem like a daunting task. Because of the work involved getting to the coils, you most certainly want to replace all eight wires as a matter of course. Considering how the price of new Bosch coils have dropped over the past year, I would replace the coil packs, wires, and plugs if the engine has gone 50K without a tune up. Use the RAVE step-by-step and you will do fine. Be sure to use quality parts as others have suggested.
