My mechanic suggested I take my 2013 to the Kia Dealership because I was having the P2191, PO300, PO3004 reading code. Replaced 02 sensors, fuel pressure regulator, and fuel pump tank seal. They don't want to keep having me dump money into the car so they sent me to the Kia Dealership to solve the P2191. The car was reading 70 PSI. I had it towed because I would lose power occasionally. At the Kia Dealership, they only saw the codes P0300, PO303, PO304. They told me I needed a Catalytic Converter. I asked them if this would solve the problem. They said they have to do it one step at a time. I told them I was having the P2191 code. They mentioned they are not reading that code. They said they can only do work on a car that the codes read. Yet in the next conversation, they would not even consider the P2191 code or diagnose that because their system didn't read this. My question is get a catalytic converter?
