How to remove MAF "tube"
 

The colukn that holds the Mass Air Flow Sensor - how is it removed?

I'm looking to replace the ETA (Electronic Throttle Actuator). Seems the MAF is required to be removed first.

There seems to be a clamp on the part - is that true? Do I remove the clamp?

This shows the part I'm looking to remove.

This shows how to fix the ETA, but not how to remove it.

Your help is appreciated.

Summary:
How do I remove the MAF sensor, so I may remove the ETA?


I will clean it, as mentioned in a thread - "Mass Air Flow Sensor Cleaner" found at AutoZone and Pep Boys.

I'm bad - yes - s600@v12uberalles.com does describe how to remove the MAF.

Once you have the MAF off, take a picture, so you can remember which way the spring and linkage goes.

Got MAF off - how is ETA removed?
 

The ETA bolts have been removed, but the ETA just doesn't want to get past th e intake manifold. I have the new replacement - but ...

Should I remove the air pollution tube, disconnected the top part of the tube - but.

Wait Wait - I just remembered I didn't remove the springs. :rolleyes:

Is that my error? I'm in Missouri and the car is in New Jersey.

Thanks

There's only one (1) spring . . . Yes, you need to remove it and make sure it doesn't 'slip' as mine did. PITA to get it re-tensioned.

Info for your car ('93 500SEL --??) is contained in Menu#24. . .

You need to work the ETA around after removing the rubber tube which will probably break . . . recommend you replace it while you doing this job. It will come out . . barely!

you will need to buy new rubber connection between maf and electronic throttle and replace all the fume hoses from rear of right valve cover down to throttle[3 or 4 pcs] ask me how i know.

Buying parts
 

U have purchased the rubber connector for between the MAF and the ETA.

I have purchased the gasket for between the Intake Manifold and the ETA.

I will but the new spring - to get tension right and the hose to the valve cover (air pollution thing).

Back to the dealer for the spring and the tubing - or does some one have the part number that I may buy it from Fast Lane.

Thanks.
