Over revving and other issues

[TristanC]

So I was rechecking the idle speed motor. And whilst there is power to it and it is buzzing - could it be sticking? I tried tapping it, but nothing happened.

I read on DMC talk that you can test the resistance as follows:
“Another way to test the idle air motor is to measure the resistance with your multimeter. A good motor should read +/-20 ohms resistance between any two pins that are next to eachother and +/-40 ohms resistance between the two outside pins.”

Now I get 12ohms and 22 ohms. Does that mean my motor needs replacing?

Who knows. Either way I’m laying the car up until I can resolve it. It’s not great driving at that high an rpm. It just keeps wanting to pull when you don’t want to.

But now I am stuck and confused as to what changed......
