[T3] Idle Air Bypass

[Daniel K. Du Vall]

I was able to get it hot enough this weekend to test and verify how it should work according to you description and far as I can tell it is. Lots of idle change when cold and blocked off and slight change after warmed so will keep it as it is and adjust the ECU as needed for the cold startup and warmup tables. Since purchased from you I am sure its functioning as should be.

Thanks,
Daniel Du Vall

Yes, the zinc bodies warp and seize the valve body. This, and the
final adjustment, are what I fix when I rebuild them.
