    This code does not always mean the coil has failed, it means there is a problem in the coil circuit or the PCM

po350 is coils 1,2,3,4 failed. The ECU has decided that there is a problem with those relays. They may be bad but check related items first. Could be damaged wiring or could need new spark-plugs. good luck.

2002 kia sedona 3.5l has rough idle replaced plugs wires and coil


this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

It could be the computer, but it could also be the wire. You can check the resistance of that wire, or simply use a known good wire to see if that is what it is.
