Abysmal perfromance of 2005 Vitz RS - Toyota Yaris Forums

it might be the issue of switching from a cable driven throttle body to a drive-by-wire system. I was disappointed with this too when I first purchased my car. do some reading on "1zz-fe throttle body swap." it makes a huge improvement in response and top end flow. it is very simple to do if you own a drill and have access to some 5mm bolts and nuts. (and a junk yard)

why are you using 0w30?

also, look inside of the air box lid. (the top) idk how they do it in NZ, but in the US there is a built in, non-serviceable charcoal filter plastic riveted to the top. take a screwdriver and pop that turd out to increase flow. there is also some good DIY's on box trimming!
