i dont think anything makes epoxy soluble, the only way to do it is either burn it off, or pick it out

Freeze Spray or pick it out.

The only experiance I have is with the Corolla TB, so that's the only one that I can say for sure fits.
Dallas, The TB can't ice up, as there is no fuel passing through the TB. To get normal intake air to ice up you'd need to run it through a really small venturi to get the pressure low enough. Hatchbackkid, do you know what the DTC associated with the CEL is? Sounds like you have an air leak. Don't forget that the silicone sealent has to sit for a few hours to harden enough to resist the vacuum at idle. |

I thought that is the only reason why they run hot coolant lines into the TB, in our cold climate if you bypass it you will have issues around zero, with rought running etc everyone around here calls it icing, do you know whats actually happening! I agree for ulimate performance you don't want it hot as a cooler air is more dense,

As far as I can tell, the TB is heated to give better fuel economy. Why a cold charge would cause those problems is beyond me.
I've flown injected piston aircraft is sub-zero conditions and they just seem to run stronger! |

Hey Nexus the TB has been on for 260 miles, and no problems, and the improvement is still there!

Is your TB still heated?

it would make sense around here because it gets very cold (0 or lower) consistantly in the winter, and on the off day it will be cool and very damp. so cool and damp, temp drops, condenses on butterfly flange, engine cools down, butterfly freezes. makes sense to me for this area at least

Saggio, my TB is not heated.
Alex, it would have to be REALLY cold and VERY humid for ice to form in the TB. When a carb freezes up it is caused by the fact that fuel requires energy to vaporize...thus when fuel vaporizes it super cools the air it's in, thus causing the water vapor in the air to turn to ice. Because there is no fuel passing through the TB on our cars, there is no way the air can become supercooled enough to form ice. The cold weather problems people are running into with unheated TB's may be caused by there being too little heat in a less-than-fully-warmed-up engine to fully vaporize the fuel in the intake port of the cylinder head, causing rough running (caused maybe by the resultant lean condition, or an over-rich ECU compensation). This is just a theory of mine, and may not be totally correct, but I think its at least a pretty good guess |

yours makes sense, it was just what seemed logical to me

Will this: http://cgi.ebay.com/ebaymotors/TOYOT...Q5fAccessories work with the '09 3-door HB? I'm planning to do the DIY listed in this thread, but I want to make sure this is the correct TB first.

Yup, that's the one. Great seller too, bought mine from them.

Thanks, Gideon. So, if I'm reading this thread correctly, all I need is the 1ZZ-FE TB and the chip from my stock TB? Anything else needed to get everything working? I'm not looking to do the coolant bypass or anything.

For those of you who did the coolant bypass, did you plug the tubes on the TB or just leave them open?

i actually pulled the tubes out with some pliers for a cleaner look and polished it up. so yes they are open.
