1994 S320 Throttle Actuator
 

I have searched and searched for 'Throttle Actuator' posts, and have found many, but none that tell where it is or how to replace it. Can someone provide this information to me for my 1994 S320?
Thanks in advance,
Glenn

PS: I would like to give kudos to the folks on this site. Since discovering it, I have:

1. Replaced my door check strap, with the help of the following post showing how to remove my door panel: http://www.peachparts.com/shopforum/tech-help/50595-w140-door-panel-removal.html?highlight=s320+door+removal

2. Replaced my A/C-Heater blower with help from the post:

Thanks to everyone!

It is under the intake manifold on the drivers side of the engine.

It is held on by four bolts. You can slide it out without removing the intake manifold, althought it is tight.
