Help Needed: Opel Corsa Misfire and Throttle Body Issues

Hey everyone, I'm experiencing several issues with my Opel Corsa. The check engine light is on, the engine is unsteady, and it starts briefly before shutting off again. There's a noticeable loss of engine power, it's hard to start, and it shakes while idling. The fault codes are indicating engine misfires (P0300-P0304) and throttle body airflow performance issues (P0068). I've already checked the fuel injectors and spark plugs, and they seem to be working fine. I'm at a loss on what to check next. Any advice or suggestions on what could be causing these problems would be greatly appreciated!

Start by inspecting the throttle body for any carbon buildup or obstructions, as this can affect airflow and cause the P0068 code. Clean it thoroughly if needed. Also, check for any vacuum leaks in the intake system, as they can contribute to misfires and performance issues. Let me know how it goes or if you have any further questions!
