2001 Firebird Misfiring

[JCbabe4585]

OK, My 01 Firebird (V6) is misfiring. When i had a diagnostic done they said it was cylinder #3...I then bought AC Delco plugs and wires and had them put in...it did NOT remedy the problem. Then i had my injectors cleaned...that too did not help. What else is there? I am getting really upset with the money that i have spent. I was told that it might be my Coil Pack? Please help me!

try cleaning the gunk'd up stuff out of the cyclinder number 3. Old gunked up oil could be causing the problem.

Try a compression test.
