Question:    2002 Kia Sedona 6 cyl Front Wheel Drive Automatic 75,250 miles CEL coming on only code is a P0306 misfire in cylinder 6. I replaced the spark plugs already. The front's are easy the rears you have to remove the IM to get to them. The rear plugs were toast, the fronts looked good. We purchased this van used so I assume the prior owner replaced the fronts as they are easy to get to and said screw the rears. The CEL is still coming on after all plugs were changed and you can feel the engine stumbling when accelerating moderately-hard. Easy acceleration feels normal. My next move is to change the coil pack for cylinder 6 and possibly all the wires while I'm at it. Does anyone here have any experience with Sedona's and troubleshooter a similar misfire issue before? Please provide any insight to help me pinpoint the problem and how to approach resolving it best.

Answer:    Not every miss fire is a spark plug so you need to check the coil /wire also you have the injector that also go be bad I would mark the coil/wire and switch them with another cylinder (may be with a front one ) and if code change you found the problem

Question (follow up):    Is cylinder 6 on the rear bank or the front? I assume it's the rear, but hope it's the front. Please advise.

Question:    2004 Kia Sedona 6 cyl Two Wheel Drive Automatic 48,000 miles I was in a recent accident that caused debris to clog oil pump. I drove another 50 plus miles before the problem caused the oil light to come on. The oil pump was changed but now the light flickers intermittently. I'm thinking the sensor could be bad, but am not sure. What else could be the problem?

Answer:    Have the oil pressure rechecked if its normal replace the oil pressure sending unit/sensor.
