yes, the 13 will fit in the 07

I sold my Yaris to my bro he came home and told me there's something wrong with the YARI.

We changed the spark plug and cleaned the MAF. When he gets home today we will clean the TB and tighten the intake.Maybe there's an air leak somewhere.

I don't have a code reader but check engine light did come on.
