Check for any vacuum leaks in the intake system, as they can cause misfires and power loss. Inspect hoses and connections for any signs of wear or damage. If the issue persists, it might be worth checking the fuel injectors for clogging or malfunction. Let me know how it goes or if you have any further questions.
