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
