1zzfe throttle body
hey guys, i recently saw someone selling a 1zzfe throttle body from a 07 matrix and he said that it can help improve horsepower and throttle response. i was wondering if this is true. and if so by how much of a difference. because the throttle response is really slow and i hate the low end speed of the yaris.

Yes, that has been tried. I believe one person who tried that got a rough idle or some cold start problems (I think it revved the motor too high or something).
Try a search on here and see what comes up.

I have it. At cold starts it idles at 3000rpm then it settles. But I still have an issues with the revs ocillating after taking the car up to 6500 (after a few pulls).

with the oscilating problem, so when its at 6500rpm, does the idle go up and down or what happens? |

After a pull when the car is in neutral (mine's a manual it oscilates a few seconds then it idles normally.

i have one. it revs up to 3 grand at cold starts and periodically revs jump up and down but then stops after a few jumps. i havent noticed a difference but my heavy ass 18 inch wheels have slowed the car down all together. if u had light weight wheels u would notice a difference

my revs jumped from 4000 to 1000 in neutral just sitting there. they never settled out. i took it off and am waiting on the manifold to put this on with.

Huh, doesnt that sound like a vacuum problem? did you epoxy the idle screw after adjusting? did you adjust it? or is there no adjustment on the 07 Matrix TB?

i didnt touch any idle adjustment screws. i saw a allen type screw but it was covered in a hard plastic epoxy already. i think it was leaking between the manifold and tb.

Why you don't just bore the stock TB better than swapping another diffrent TB.

After a week I got a Cell I scaned the car and it threw a code (wich I don't remember, sorry) it is an "Iddle malfunction". I'll work on it later in the week, but the car at least doesn't feel worst. It functions good and I just installed the 10% undedrive pulley and.... what can I say..... I love it!!!! But I'am suffering with the fat TRD18's ...... 18's ain't good right whooppee777??? LOL
