Ok... To make a long story short... Some a** hole put a hole in the part in front of the throttle body. I don't know the name of it so I can't call around to price the part... What is the name of it???

 

any help anyone??? I need to know the name of the whole entire piece!!

 

Are you talking about the black piece with electrical wires mounted on the throttle body or the breather housing that actually sits in front of the throttle body mounted to the radiator support? Check out the "sticky" on this site for the parts manual that gives a picture and name of the parts as well as the GM part number.


Oh. my bad, I just seen the hole you are talking about. That IS the throttle body!

 

oh ok. i knew that was it. thanks alot

 

To me that looks like a pressed-in inspection cover that hides an adjustment screw below (that you shouldn't normally be playing with anyway). To pop those out, you put a hole in it with a hammer and punch (like you have), and rock it out. Look inside the hole, if you see something that you can turn (screw slot/hex slot, etc.), don't sweat it. A hole in an inspection cover isn't going to hurt a thing.

 

Yeah, that's the anti-tamper plug for minimum idle speed adjustment. The factory sets the throttle blade to a certain "open" amount during manufacture and then plugs the adjuster screw hole so nobody messes with it. Except somebody *did* mess with it.

This is kind of bad news because when somebody messes with the minimum idle speed screw they're almost always trying to fix a problem without knowing what the problem is. Something else is probably screwed up (often a vacuum leak) and they try to compensate by adjusting the idle speed at that screw.

The hole itself is not a problem -- there's no no airflow through it. The fact that somebody messed with the screw under the plug is the problem.

 

I was thinking that someone may have been having a problem with a bad IAC, and tried to adjust the idle the "old school" way.

 

so you are telling me just by adjusting the screw ,which someone did, will cause the hole?

 

That's a tamper-resistant plug that you punch or drill a hole into, to pop it out with a screwdriver, punch, nail, etc. Then you can access the screw below. It just means you know someone was messing around under there, but the hole hurts nothing.

 

thanks alot man
