wow excellent idea!

*tk-421* · 03-08-2009, 04:58 AM

Awesome info! Thanks

WolfWings · 03-08-2009, 08:31 AM

This bit of info let me dredge up something that might explain why earlier folks had fewer issues with the throttle-body swap.

Some Corolla's came with throttle bodies with ID #22041 on the chip housing. Others have that problematic chip-housing with ID #0D031. What'cha wanna bet the #22041 chip is special in some way? :-)

DUDE YOU ROCK!!!

Thank you for solving this issue for us. I can now finally install mine without a CEL coming on.

Does this also solve the high rpm when cold problem?

This is great. I am so stoked to get this on the car. It truly makes a difference that can be felt.

*tk-421* · 03-08-2009, 06:20 PM

Do I need to drill through the bolts in order to crack open the TBs? Is there a better/safer way to accomplish this?
Also, what is the best way to trim the intake tube to fit the new diameter?

AlexNet0 · 03-08-2009, 06:35 PM

I believe they are riveted, so you will most likely have to drill them out. or be really careful prying them out

Edit, nevermind, he beat me to it.

yarstar · 03-08-2009, 10:16 PM

Cool. I'll take the high rpm at cold idle if we can get rid of the CEL.

Thanks again T-Sport. This made my day.

AlexNet0 · 03-08-2009, 10:20 PM

mind if i make this a pdf for sticky posting if the mods want it?

Arkhangel · 03-08-2009, 11:41 PM

ok so bigger TB means more air coming in? What is the performance gain with it?
Good? i have stock intake with K&N Drop in filter, do i need to change my intake?

mikenacarato · 03-09-2009, 12:23 AM

can anyone confirm after driving over 100 miles that no cel comes on?

BTW this thread is awesome! thanks for doing this!

gwasabi · 03-09-2009, 01:18 AM

no CEL over 100 MPH

LtNoogie · 03-09-2009, 02:00 AM

Good work on figuring this out. Where did you get a 1zz tb? At a junkyard?

PETERPOOP · 03-09-2009, 02:28 AM

this it?

I've had my 1ZZ TB on for over 20K miles and never had a CEL or oscillation of any kind.

You probably got a defective junkyard TB and swapping out that casing fixed whatever problems you were having with it before.

eTiMaGo · 03-09-2009, 07:16 AM

that's another possibility, but it would be interesting if you could look at the model number on yours, to test WolfWings' theory!

That is it. I bought it from this guy here in Georgia. Really straight up guy and the price was way lower than what I found elsewhere. They get all there parts used off of totaled cars. Back in January when I got mine, he said he had 4 more.
