W126 MAF Sensor?

I'm starting to doubt if this car has one based on search results. Does it have one and if so how may I clean it?

On a side note I found a guide to remove and clean the throttle housing. But it makes no mention of what appear to be AC lines to the fuel distributor. I assume it best to leave those connected and just move the distributor asside?

Thanks much!

Car has air flow position sensor, no MAF on CIS-E fuel systems.

Yes, the Air Flow Meter is what you see when you remove the air cleaner. There is no Mass AFM, nor would one have any real function on CIS.

Thanks guys. Good link too, have not seen that article before. I may have fixed my hot startup issue already. It would stumble and stall, stall for sure under any load such as AC or power steering. New O2 helped but this morning I spent 30 minutes dialing in the duty cycle. At idle it was going for 98%! Now I am at 60%. One any other car I would have blamed the MAF sensor.
