When cleaning the throttle body, and replacing the hose from Air Mass Flowmeter to intake, I found that there is liquid in the intake manifold (to be seen in the picture)

Should it be dry , and should I suspect any thing wrong with my engine?

any suggestions of what I should do as maintenance/ repair?

I just cleaned the inside of my intake manifold. This improved the warm start and the idle significantely. I am not sure, what made the major difference: dry and clean pipes, a clean pipe next to the throttle valve (there are 3 holes, one of them was sealed with dirt), or the new gasket.

I had the same founding.

the little hole was dirty and after cleaning has given a much bettre idle at warm.

I am wondering if the flap is correctly adjusted in zero position.

Should the hole 1 be above the flap or somehow in between as on the picture?
My guess is that the hole @1 has to be above the flap and as I do not have the CD so I expect to get advice from anybody who may know

Can anybody tell what is the procedure for adjusting the flap at idle?

The hole @1 goes to the thermovalve via vacuum line

The 2 holes @2 are in fact connected inside the throttle body and act as one, they go to the regeneration valve via vacuum line on the front left fender.

No body has any idea or experiene or procedure from the repair manual to adjust the zero position of throttle flap ?

It's called the "air flow sensor". Go to:

No, this is the flap underneath the air flow meter. I have never heart that this flap has to be adjusted. Why do you want to do so?

I would assume that the flap (at least its lever) has a stop which will (should) be reached.

Indeed this is the flap of the throttle body (my car has no speed control)

I used to be familiar with carburetor cars with adjustable idle, and did not know ( before I joined this great forum) that on a 260E the idle is not adjustable.
Then I moved the screw which acts as the stop of this flap -see picture attached, (btw this screw is almost unreachable when the Air mass Flow sensor is on).
Trying to get it back has been very problematic with the engine on.
These days I took everything out and cleaned the holes and the flap zone (which improved the idle). My car has 380 000km and is runninng great except ilde and some erratic stalling.
Now everything is out and I wish to adjust this flap at its nominal position.

Nobody can help???

I have a pic of my flap before I cleaned it. I would assume, that both holes @2 are above the flap. Otherwise I wouldn't see the bright spot at the lower hole. But look for yourself!

To be sure, you could visit a junkyard and look at a used part.

the upload didnt work

Thanks ThomH for the picture.
my flap was almost as sooted as the one on your picture.

So I would guess that the lower hole of both sets have to be above the flap ( 2 bigger holes@2 and 1 smaller @1 on my picture)

The screw and locknut in the photo is the idle throttle stop. On a KE equipped engine I believe there is a procedure to check the idle control valve duty cycle and adjust the stop until the duty cycle is in the proper range, or their might be some other measured value to set the throttle stop.

I've never looked into the procedure in detail, but it should be on the maintenance CD.

Duke2.6,
Indeed that is the function of the screw:" to stop the flap". I guess the flap may have to be completely closed or very little open.
I am looking for the procedure because I do not have the CD.
I guess the most down holes (@1 and @2 on my picture) have to above the flap but I am not sure.

btw I bought my car new and it has a 5 speed manual gearbox

ThomH,

Do you have the picture after cleaning?
