Customer Question

i have a 2002 KIA Sportage 2whd with 2.0L eng. it ran fine until we changed oil and spark plugs. now it will start and run on 2 cylinders. OBD2 codes come up 300,301,303. I changed both coils. still the same. revved a little and got a 604 code. checked crank sensor- it works. ordered andinstalled a new PCM. still no change in codes and misses the same.

Hello Im Chris and I will assist you. As I read your story you said it ran fine until you changed oil and spark plugs. Im wondering about the spark plugs. Did you try replacing them again?

Also is your tachometer acting up?

Also keep in mind that a p0604 is usually a bad PCM. Clear the code and see if it returns.

If it returns it may need to be reprogrammed or replaced.
