I had a guy change my spark plugs and wires yesterday and now it's missing really bad. I believe that he got the spark plug wires crossed. If so, how do I correct it?

It sounds like you're right. Driver's side front is number one, then 3,5,&7. Pass. front is #2, then 4,6,&8. Your firing order is 18436572. Note: It's easy to get 5&7 crossed

Good evening

I will attached the cap arrangement for you to view so you can verify the position.

also, if they are ok, it could be a spark plug that was either not gapped correctly or dropped and was damaged.
