I recently purchased a TBSS Throttle body and I have yet to install it but when I got it I noticed the blade isnt closed all the way perpendicular to the unit it is open about 5*. Is this the way it is? I currently have a 5.3 Tahoe throttle body and the blade closes all the way. Did i get ripped and buy a broke unit or is this how the unit is when it is closed?

 

A picture would be nice There's supposed to be a gap...can you push it closed further than it rests naturally?

 

i know i sold one to a member here a dbw and the blade was completely closed. but i cant say if its suppose to or not sorry

 

Can the pictures be seen?

 

hmmm it does look open alittle !!!

 

thanks that makes me feel alot better! thanks skeet for the quick reply I dont think I was going to be able to sleep til i got to an answer.

 

yep 100% normal.its the same on my ss's tb

 

Would it close all the way when you hook it up the the truck?

it does when you first turn the key to run , it is a test it performs to make sure its sweeping. when idling it is cracked for enough air to keep the engine going so it really does not stay shut.

 

so those ones dont have IAC valves like my cable tb...
