Try Seafoam first, you may have some dirty gas or injectors.
Next check outside spark plugs for condition. They should be clean with tan ceramics. (inside plugs should be same as outside plugs so check outside first. If they look good don't check inside plugs. I changed mine at 25K but it wasn't necessary.
