All cars both manual and automatic have throttle bodies. It's not a recommended scheduled maintenance item. It can't hurt the car, do it as often as necessary. If you take off the intake tubing and if it's dirty inside there clean it. I have neglected to do this but will probably clean mine tomorrow and check it every 10K miles or so.

Just did this to my coupe a few weekends ago.
I was having issues where the car would almost stall at start up or in stop and go traffic. Now its completely gone and the car runs like new.
The amount of gunk and residue that came off was remarkable. I actually had to throw away the shop towels after I was done as they were completely black.
This is going on my list for annual/bi-annual maintenence.
To the OP: I owe you a beer.

The 3.7L engine uses VVEL for throttle control. It vaires the amount it intake valve opens to control the amount of air flowing into each cylinder.
It does have a throttle body but it's just there incase the VVEL fails; it remains fully open at all times. If you're having throttle problems and have the 3.7L V6 then you should go to your dealer.

Just an "update". Some one posted a video on YT of a G37 during start up showing the problem.
YouTube - G37 can't maintain rpm
I guess it happens on the VHR just as bad as the HR lol
