Hard idling, oscillating fixed

[Denis]

Thanks for replies about my bad idling 2.3 l

I removed the idle stab valve and plugged it to my batterie charger. It seems that was ok but i cleaned it anyway. It was lot of black smock on it , same smock than in the ouput exhaust.... the engine run much too rich for a wwhile....must be lamdaa sensor.

So i cleaned it with brake cleaner and well plugged it in place. Maybe was not plugged propely before.

It runs good now
