Hello guys, I have an Escort tournament MK7 with 1.6l Zetec engine 90hp and unfortunately have problems with the idle speed. When I start the engine, the engine always turns up to over 2000. when I drive, it even gives gas on my own. When I step on the clutch, it turns up to 4000 already. but all this only when it is cold. Last week I changed spark plugs, air filters, oil and oil filters, but unfortunately did not bring anything. Yesterday I then realized that the Crankcase ventilation valve was completely emptied. I then took that apart and tightened the spring a little bit and re-learned the control unit. Since then it spins up to 3000 or even higher at the start and then fluctuates extremely between 1000 and 3000 in idle mode. I cleaned the idle control valve already. Unfortunately did not bring anything. Does anyone have any idea? Thanks already Marc
