Hi all
I (actually we, I always get generous help from another forum member) have cleaned the ICV and replaced its vacuum hoses. The hoses were due, the ICV was relatively clean. We also replaced the air mass sensor potentiometer. Doing so, I realized that all the vacuum lines are very brittle and I will replace them as well. In addtion, we installed a new air mass sensor potentiometer, the old one was worn.
However the stalling condition did not get cured. In a next step, I will therefore get at the throttle control switch (is this part also called microswitch?) and linkage. I will also replace the coolant temp and intake air sensors on this occasion.
I will keep you posted, have a nice day, Bruno
