2020 Kia Stinger GT Line Limp Mode

When I was running the diagnostics I was getting atmospheric pressure readings from the computer and when I would accelerate the engine it would go up 2lbs during some boost so it appears to be working. Its getting beyond me with what is wrong with this car.

Yea it may be time to roll it to the dealership. Let them diagnose it. Then you could get the parts and do it yourself.

After taking the car to the mechanic they replaced the fuel pump and that seems to have fixed the issue. I have never seen a fuel pump fail and the car report more pressure than it should have. Can it fail providing too much fuel? Never seen that happen before.

Cool you got it fixed. Yea codes suck sometimes to help diagnose. The fuel pump seems to be an issue with the 2.0 thats starting to show its face. Quite often in my circle of readings. Only reason i mentioned it originally.
Im guessing there has got to be some sort of regulator on the pump that failed, so in turn it couldn't keep up. My theory is similar to oil, too much is just as bad as not enough, creates a strain. Again just my opinion.
