Error codes , po500 , po157 and po152. Engine light stays on. But flashes while motor bogs down.

I attached the info about this and testing about these codes. The fact that the light is flashing shows that you are doing damage to the exhaust system due to the amount of unburned fuel that is going through it so we need to run through this testing to find the issue before we do much more driving.

Run through this testing and let me know what you find. Thanks.
