2001 Mustang, Rough Idle, misfire on cylinders 1 and 3

Hey guys, well, i have a 2001 mustang convertible, and i went to get my car washed yesterday. When i left the car wash, the car started misfiring. I was wondering if someone would happen to have a spark plug diagram for the 2001 v6 mustang. Well, a picture would be better, with microsoft paint or whatever; putting 1-6 on the different plugs. Please help, I've got a big trip planned, and don't have extra money to spare on the shop to fix it.

also, if you think it could be something else wrong with it, let me know what it could be if you've had this problem before.
