My Kia Optima Turbo GDI has recently developed a knocking sound. I took it to a mechanic for inspection, and it was confirmed that the filter leading to the cylinder was blocked. Consequently, I had the cylinder and camshaft replaced. However, since then, my car has not been functioning properly. It can't accelerate beyond 40, and I have to turn off the car and restart it to get it moving again. Additionally, if I go beyond 30, the car stops. The car has been scanned, and the turbo has been checked. I was told the turbo is okay, but the car still won't accelerate beyond that limit. This issue has persisted for the past week.

Those are code that came out when the car was scanned, the readjust the timing and fix the turbo but still the same thing

Your timing wasn’t properly set when the cylinder was replaced. You could have an issue with the boost pressure sensor or its circuit.
