Default Cayenne S

Hello, I’m new to the forum and to the Porsche community (previously drove BMW). I have an issue with a Cayenne S 9YA, V6 324 kW. The car shows a fault with injector no. 3 – error P02F000: Cylinder 3 fuel injector – Unreliable signal. After a few seconds, it also throws P036300: Misfire detected, injector locked out.

Does anyone have any idea what could be wrong? I’ve checked the wiring from the injector to the ECU.

The km or miles have not been reported yet. The 324kw is kilowatt hours and converts to 434 hp. I am curious about the km or miles since I have not read of the problem the OP is having and I have had a 2021 Cayenne S for 5 years and plan to keep it another 5.
