1zzfe throttle body - Toyota Yaris Forums

lilman717 · 01-04-2009, 11:18 AM

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.

lilman717 · 01-06-2009, 07:20 PM

do you think it's worth it? and how much did you get it for.... i have a sedan automatic

whooppee777 · 01-07-2009, 07:28 PM

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

mikenacarato · 01-07-2009, 09:33 PM

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.

AlexNet0 · 01-07-2009, 10:13 PM

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?

mikenacarato · 01-07-2009, 10:31 PM

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.

ztrack157 · 01-08-2009, 02:56 AM

Mike buy some gasket maker and use it you should be good after that.

mikenacarato · 01-08-2009, 03:32 AM

i have black silicon i was going to use, i also have gasket maker as well though..hmm. i dont feel like messing with it at this moment though haha

ztrack157 · 01-08-2009, 04:05 AM

Ya I'm waiting to put mine on this weekend. I'm still in the R&D phase of my intake manifold. I have a Buddy at Canepe helping a little.

mikenacarato · 01-08-2009, 04:07 AM

what are you doing with it?

kimo · 01-13-2009, 02:00 PM

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

Will cost $100

ddongbap · 01-13-2009, 02:22 PM

I don't know if you can bore out the stock TB 1/4th of an inch.

YarisPR · 01-14-2009, 11:17 PM

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

knucklehead · 02-02-2009, 10:17 AM
