Hello,

An engine can have low power for several different reasons. It could an issue with the spark plugs or not getting proper amount of fuel.

Typically when a vehicle shakes and idles rough it can trigger the check engine light. Is your check engine light illuminated?
If so you need to get it scanned to retrieve the codes. Which can help diagnose the issue.

Please let me know.
Thank you.
