(1) Answer
review when last tuned. it may be due.
rec. fuel system clean. ethanol treatment to 1 tank premium. ethanol blend in fuel causes build up in fuel system(possibly fouling injectors), combustion chambers. exhaust and causes increased wear to spark plugs.
get diagnostic run to find any other issues u need to be aware of.
