Is this throttle body normal? (Video)

[00firebird]

While tearing everything down (upper/lower intakes) I think I found the vacuum leak my car has been having? My throttle body plate does not sit flat.. is this normal? Here is a video you should be able to tell.
I also can't service anything inside because the side plate is riveted in.

What's it off of . It's electric the motors controls the blade . Also eliminates the need for an IAC stepper

It's off his 2000 Firebird.

correct! it is electronic, but i'm still not sure if that is normal?

ls1? i thought they were drive by wire. hmm

3.8.....looks normal. Who did the tune? and are you sure vac leak wasn't elsewhere? bad pcv valve?

It's normal for the 98+ throttle bodies to not fully close? Not having the IAC stepper throws me off from the LT1 throttle bodies.

I think it's a fly-by-wire thing. I still have an IAC but cable TB

unfortunately it isn't servicible thanks gm.
Tune was done 3 years ago, didn't get vacuum leaks til 6 months ago.
PCV valve did have fresh oil all over it.

That is normal. The electronic TB cracks the TB blade open in place of an IAC. That is the default position.

thanks, so the mystery continues..

I would check PCV routing and make sure its correct. IIRC theres not a whole lot of vacuum lines on the 3800 motors, just a few I thought. Is your HVAC working correctly? Power brakes? Have you hooked up a vacuum gauge to it yet? How do you know you have a vacuum leak? Not doubting you, just trying to help figure it out!

Theres alot more info on it here http://www.fullthrottlev6.com/forums/showthread.php?67227
PCV just sits in the upper inake and didn't have anyhing connected to it, just a plate on top. I did backflush through the heater core during the coolant change, but it doesn't show any problems and works better than it did before the flush. Hoses and connections all look fine. As I've currently ripped down my upper/lower intakes to do the gasket swaps, I figured that would be the only other problem. So far I don't see many lines, everything is just electrical connectors. There were a few that looked like mini spark plug boots that were either vacuum or emissions lines but they all looked in great shape too.
