So I took you advice and I gathered a lot of info from removing/plugin connectors but not sure how to decipher it.

Yes when ignition on it vibrates softly.

So I am basing these tests in these three connectors:
1- Cylinder head temp
2- Speed sensor
3- Reference sensor
Am I right?

As soon as I unplug it, the car runs like crazy and just revs really high.

The car becomes more sloppy and runs rougher, escalating between 1500 rpms and 500 rps at idle. When I plug it back in, its a bit smoother bit still rough and sloppy.

So when I unplug it car runs sloppier.

Yes when I apply little bit of throttle and switch opens the cars notes and and revs a tad bit higher. when switch is pressed it becomes calmer.


Two more things:
1- When I unplug the speed sensor the car dies instantly, is that normal?
2- When I unplug the reference sensor there is no difference at all. The car idle and roughness does not change at all.
Do I have a bad reference sensor? The reference sensor is used for starting the car. But is it used when the car is running? I had a GMC that had a bad crank sensor that had similar issues to the Porsche. Did I identify a broken sensor?
