An erratic idle is usually noticeable when mooring. Often, it's not a major repair, but a minor issue that can be quickly narrowed down with a bit of systematic troubleshooting.
Common Causes
Inaccurate throttle body adaptation, dirty or worn spark plugs, and small leaks in the intake tract are among the classic causes of an erratic idle.
