Hello, with my MX5 NA 1,6l 90ps I have tried so much, but it still doesn’t run properly as it should. I have set the idle speed (despite that it runs at 1200 revolutions, sometimes 850). I have changed the coolant temperature sensor. And I have replaced the crankcase ventilation valve + hoses. Ignition plugs + ignition cable + ignition coil are also new, everything from NGK Nevertheless, he wants again and again (only at the idle level ode r when driving only when the clutch is kicked). Sometimes it runs at 200 revolutions, then I turn it off and on again and it then runs at 1000-1200. the speed also varies slightly. No matter whether it is cold or warm – it is always the same. Unfortunately I don’t know any more and hope for solutions Thank you in advance, LG
