Kia Troubleshooting Questions? Ask a Mechanic
Hi. Those motors do not like to get hot. I would not be surprised if the headgaskets are blown. Since you do have some backfiring, I think you should have the timing checked like you mentioned and have the headgaskets checked.
You could have melted one or both of the cat converters and now the exhaust is plugged.
I thought that had cats that are part of or bolt to the exhaust manifolds. How would you remove them? Also, if it is backfiring then you should check the timing. You could try disconnecting the mass air flow sensor to see if that makes a difference.
