vacume leak on throttle body
I have a vacume leak on the bottom of my throttle body and im pretty sure its the seal where the butter fly shaft goes through it.My question is how difficult are they to replace and where can I a diagram of the tbi?Thanks AaronWhile driving remember this rule of thumb,If another driver switches lanes infront of you cutting you off causing you to slam on the brakes to avoid a collision that they almost caused its your fault and you should be happy that they flip you the bird when you lay on the horn.

I did find a diagram online of the throttle body thats used on my truck.I also gave a wrong description of the shaft where the bad orings are.Its the throttle shaft on the bottom of tb.Has anyone here ever replaced them?Am I going to have to get a complete rebuild kit for the TB?

Yes Im sure I sprayed carb spray in the area of the shaft and my idle will go up.Its also making a whistling noise from the same area.
