Possible Engine Control System

[snipe99999]

Thanks for the help in advance.

My check engine light has been on for about a week and I am taking it to the dealer. Well I took off the JB4 and the car is now announcing possible engine control system issues Kia recommends service. Before it was just the check engine light no announcement. Any idea it would do that after I removed the JB4? Is there a way to turn that off? Thanks

Do you have a code reader? What does it say?

I know what the problem is. It's a miss fire most likely the coil pack since the spark plugs have already been replaxed. My question is why would it just be the light with no audible warming for days until after I removed the JB4? Thats exactly when the audible warning started.
