We have a 2005 Kia Sedona Van. It is jerking really bad. We took it by Auto Zone and their tester gave us codes of p0300 thru p0306. They said it was an electrical problem. There are so many things it could be. Do you have an idea where we should start. We put some Lucas injection fluid in it last night but we are only about 4 miles from there so it hasn't run very much since. The car has almost 82,000 miles.

Hi there,

I would sart by checking the timing belt. It's pretty common when you get to this mileage for the timing belt to jump time and cause multiple cylinder misfires like this.

You can also check for vacuum leaks along the intake manifold by spraying some carb cleaner along the intake when the car is running. If the idle smooths out or increases then you have a leak.
