Does a clamp belong on the flex duct resonator hole ? 2002 STS
I recently bought a 2002 STS and took the air intake assembly apart this morning to check the air filter and clean the throttle body (though it might improve the fuel economy a bit). When I took the upper assembly off the air intake (not sure what it does or what they call it, maybe a muffler or resonator) there was a worm clamp around the connection going to the air intake tube and it appeared that it was not put back on correctly. STS Air Intake.jpg The clamp doesn't like it belongs there or is mounted the wrong way around it almost seems that this would snap together without a clamp. Does anybody know if this is correct and/or which way the clamp should be oriented.
That hole is for the intake resonator assembly. The engine will not run correctly with that hole open or not properly clamped due to the divorced MAF next to it.
Go to a hardware store and find a 2" pipe cap or a proper sized PVC pipe cap and clamp it in the hole - discard the resonator and use a suitable machine screw in place of the Torx screw in the top of the PCM box cover.

The original factory clamp on that hole neck was a non-adjustable spring clamp - most of them have been replaced by your band clamp. I discarded my reasonator 7 years ago and have never regretted it - it sure makes engine and parts checks a whole lot easier.
FYI, The transmission is a dry sump unit - there should be NO FLUID on the transmission black plastic dipstick with the engine off. Check level with the engine hot (> 10 mile run) idling in P on a level surface. That little metal wiggle cap and hose clipped to the throttle cable bracket is the transmission vent hose.
What is the build date on the sticker on the driver's door edge ???
Thanks for the quick reply! I think I have the resonator back on correctly now, the last person didn't screw in the Torx head stud that the resonator slips over, once I corrected that the resonator lined up perfectly with the hole in the intake tube. I couldn't find a good position for the clamp where I could loosen it with a screwdriver so i used a ratchet. I'll probably take it apart again next weekend to check the transmission level as you suggested.
