Whaaaaaaaaaaaaaaaaaaat? Please explain what happened. I'm scared, I'm scared for my life now.

jkuchta · 05-16-2009, 07:35 PM

So what went wrong? Do you know what the CEL code was?

Please tell me step-by-step how you installed the 1zz TB so we can figure out what went wrong. I've been running mine without fault for a few months now...there's got to be something simple that can be fixed and will clear up the whole problem.

And eii, if you want to go for a ride in a yaris with the 1zz tb install that was done correctly, PM me.

CEL was gone. Car completely died and wouldn't even idle. Start it up and it woul ddie instantly. I used the original gasket plus gasket maker, I did the coolant bypass, I did the chip swap. I did everything it just didn't work out for me

That could be pretty much the 1ZZ T/B itself being the problem, try another different 1ZZ T/B or try the 2AZ-FE 2.4L T/B.

remember! failing is the beginning of success, it wasn't easy for me either

doesnt sound like the TB unless a wire snapped somewhere.

Stocker works flawless though so it isn't a wiring issue.

Oh I was just kidding, hehe

. I based my install on the guide post you made earlier in this thread (thanks btw) so I'm sure I did it correct. I just get that < 1 minute 2.5k-ish cold idle start. Other than that it works great, I was just wondering what happened to demon. I just did the coolant bypass this morning, its more responsive and I definitely feel some more power. Cool stuff

kustom play · 05-16-2009, 07:56 PM

yea thats crazy my CEL went off and its been running great!

jkuchta · 05-18-2009, 02:35 AM

Bummer...

Do you know what the code for the CEL you were getting was? It may provide some clues as to what caused your problem.

bieniman · 05-20-2009, 09:35 PM

Guys,
I've been following this mod for a while now,

If I'm correct the newer yaris models have electronically controlled TB. Well, I looked under my hood and see sort of like a cable running from the pedal to the TB, I can rev my engine by turning this swivel.

Yes, this mod only applies to the Drive by wire system that is in the ( i believe) '05 and newer

I'm not 100% positive on this but the scion xa/xb owners have done a swap with an older 1zz throttle body which is drive by cable like yours. check the forums @ scionlife.com you should be able to dig up more info.

bieniman · 05-20-2009, 09:38 PM

O yeah forgot to ask.

Can I do this mod also to my , Vitz Rs 2001?????

MGargano · 05-21-2009, 01:53 AM

The chip swap was working fine for me... no CEL or oscillation... until I had to disconnect the battery to swap the steering wheel. Once I reconnected, oscillation & CELs galore.

jkuchta · 05-21-2009, 04:10 AM

What codes are showing up?

Just saying you have a CEL is kind of worthless unless we know what the code is. It could be just a case of needing to adjust the idle set screw, or a number of other things.
