Good evening together, I’m really depressed at the moment, because my MX-5 has been having a problem for months now: the idle speed. First of all: The car drives quite normal, pulls well and everything is great. Only the idle speed is in both cold and warm condition (and we talk here after no matter how many kilometers driving time) every time at 1300 revolutions and fluctuates extremely. It also sounds totally unround, you always hear totally that it turns so high and you hear that fluctuate naturally I have also not listed a video on YT under, so you can listen to the whole thing – and watch: https://youtube.com/shorts/It4T34-031I I have already checked / exchanged the following: – False air tested with a fog machine (everything dense, smoke didn’t come out anywhere) – Coolant temperature sensor replaced – crankshaft sensor replaced – crankcase ventilation including all hoses – replaced a torn hose at the top of the valve cover – ignition cable + ignition coil + Spark plugs exchanged – The screw for the idle speed is completely turned in, I can’t turn it in any further. As soon as I turn it out only minimally, it turns even higher looking forward to answers.
