Re: KIA Sedona 2002. Stuttering, running rough, hesitation.

I have a KIA also and heres what i experienced. At about 70k miles my
ignition coils and cables started acting up. It did the exact same thing
run rough then once it got warmed up no problems. I took out the presumed
ignition coil and tested it and it was defunct plus i found out kia has
redesigned almost all there parts like 2 or three times. Before you do
that though just change your spark plugs. If no improvement then try your
coils.
