Just to add a bit to this thread. In English, when the idle speed is changing and does up and down, it is often written that the idle is 'hunting'

This means it is 'looking' for a stable idle but not finding it.

Well done guys and also Manovlov for your hands on work!

Then it is wiring problem for ECT from wiring loom side.

It have to be it...it's a classic bad ECT sensor symptom or it's wiring.

Since ECT is oe and brand new...the connector or wiring for it from wiring loom side is bad.

Hoooray Manov! I hope you did well on your test.

I hope it went well for you. I still have various automotive books from my time at a community College, '79 to '81. (I'm old)

Congratulations and all the best to you. This is a great community.

Great story, congratulations!
