So in tracking my O2 code problems (other thread) weather broke and I decided to build a smoke machine and test for vacuum leaks. Smoke machine was successful and for the most part no vacuum leaks which was good. Except for one little wisp of smoke that came out behind where the throttle cables / spring attach. This I would guess is coming out from where the shaft enters the throttle body. Does anyone know if this involves a seal or complete replacement?

 

yup mine was leaking there as well i never did repair it

 

Thanks for the reply. Do you think it had any real impact on the performance? Mine is very slight.

 

it will impact performance as it loses vaccum there

 

I have the same wisp of smoke at the pivot for the throttle body. Is there a fix or rebuild kit? Or just let it be? I am chasing a p1415.
