    Check for any check engine light codes, this is the best place to start, as it will help you diagnose the issues.

    Start with checking for trouble codes stored, then the next best thing to do is look at live sensor data with a professional grade scan tool, you can see fuel trim figures which may imply a vacuum leak or low fuel pressure or delivery volume. Best to start with the basics and proceed with proper diagnostic trouble shooting.
