Engine refresh ?

[David C]

My brother took my car today and he said that the engine feels like its sluggish compared to his Yaris. I have to admit I kinda feel like it's been a little rougher/louder and the car doesn't seem as smooth as it uses to when I bought it 2 years ago. It has 210 000km, 2007 HB auto.

Last when I checked the spark plugs a few months back one was reaching end of life and the others were middle (clearance check). I never had the engine knocking or misfire, never any trouble at startup. Do regular 8000km oil change.

I'm thinking maybe new spark plugs, new intake air filter (been 1.5 years, but isn't dirty) and... that's about it that I know of I cane o myself. Not sure it's gonna do much tho. What about those injector or throttle body cleaning etc ?

Personally I have no problem at all with it, but maybe there's something the car could benefit from ?
