misfire after changing plugs and wires

i just recently changed my plugs and wires. I listened to a friend and put a non-fowler in one cylinder because i'm having problems with excessive oil burning. the plug either backed out of the non-fowler or just wasnt getting good fire and burned up the plug after 30 mins on interstate. It started misfiring after that. i changed the plugs again thinking maybe i had faulty plugs but i'm still getting a cylinder 4 misfire on the diagnostic reading. can anyone help?

 

did u check the gap on the plugs and are the wires in the correct places.

 

the wires are right. I changed them one at a time. And i called the dealership to get the diagram to make sure. the first set of plugs i bought from autozone. the second set i got from dealership. the wires are duralast wires from autozone. should i get the wires from the dealership?. i'm thinknig of bringing it to the dealership and let them fix it. but i dont want to spend money if i can fix it myself. does anyone think it could be sensors?

 

thanks. i hope i can be some help to others. but i'm having such a tough time figuring out this misfire thing myself.
