Most probable: Poor MPG, acceleration, & possible rough idle (if very dirty).

Default That symptom could be a bad spark plug(s) or a dirty fuel injector(s). Have you checked the plugs...
cleaned the injectors?

Default Just checked
just checked one of the spark plugs, it looks OK. Fuel injector, planning to use fuel injector cleaner, what brand is the best?

Thank you.

Check for vacuum leaks. I had two that I took care of and now my low idle with shaking, along with hesitation on acceleration, are gone.
Good luck
