I have read some threads about adjusting the EHA-valve with 1/4 clockwise.
Do someone know which are the original setting without special tools?
How many turns from the bottom for example?

Hello,

You need to be very careful with adjusting the EHA.

The problem is that the screw is tiny and you can adjust it without knowing your doing it.

There other adjustments that can be done before screwing with this valve.

Before doing anything with the EHA, where are you with your car??

Whats the problem?

I had hesitation problems with my car which nobody managed to fix. I tried to change the EHA-valve and everything worked better exept at idle.

On the old EHA-valve I just want to experiment on the setting to see if this is the couse of my problem.

I misunderstood the text in another thread here where I thought the setting shold be 1/4 turn from the bottom. I realized that it was 1/4 turn cw from the original setting.

Hello again,

The EHA valve adjustments are the last resort! You need to get your mixture corrrect first.

Please review the info on the attached link.........

To do the analysis of your problem you will need a Digital Multimeter!

Check your air meter settings with the Dig meter.
Check your Lamda/O2 sensor settings, is it working etc

good luck
