Can someone show me the picture and give me some guild where is the :

2)injection connector
 
 of Hyundai sonata 2002
 
or the way of changing it.
 
I need to repair by myself, scanner show me :
P0305 cylinder 5 misfire detect

For a misfire, the first thing you should do is change your spark plugs and wires.  Have you done that?

ok.thank you Doohickie.
spark plugs all new, i think is the wiring problem
after i pull out and plug in and tight up all the wires, now the car is ok
but not sure still got problem or not.

Good luck; I hope it works for you.
