Hello folks, I need to order an Idle Speed Control and Idle Air Valve for my 117.963 engine (500SEL). I looked up the seller's websites under 500SEL and although the items look similar to what I have in the car, the part numbers (last digits) do not correspond. My question is, can I go ahead and install them in my car? They did indicate that the parts were for the 500SEL. I'm asking because it's a long way to order where I come from and I can't risk any mistakes.

Also, the car I recently got came with a nonfunctioning Idle Speed Control and Idle Air Valve, instead a rubber hose was inserted into the Idle Valve branch (thereby narrowing the opening) coming from the Idle Air Distributor, while the hard plastic hose from the Idle Air Distributor to the intake(manifold) was plugged. The owner said the car is driveable after warming up, but is it? I'm not about to risk messing up an engine, although I think I need to get the engine running once in awhile instead of just letting it sit there while waiting for parts. Any help would be much appreciated guys, thanks!
