Engine Speed Sensor....

Hi peeps...
has anyone heard of the Engine Speed Sensor??
I found an old thread on the web and it sounds like it will cure my mystery starting problem as the guy seemed to have the same problem and then put this on the thread.....

From what I can tell, that sensor tells the computer the speed of the crankshaft, which controls spark timing and fuel injection. In my particular case, the sensor was putting out a weak signal, which is really weak in starting conditions (low RPM, low battery). The problem was also heat related -- if the engine was cold, it worked fine. If the engine had been running for a while, it worked fine. If the engine had been running, then shut off and sat for about 20 minutes, it wouldn't work until the engine cooled down further

just can't find a lot about it and wondered how easy it was to fix?

Thanks....

Just thought I would close this thread and let you know that although not as easy a job as first thought, the sensor got changed today and car has been fine since! Starts every time, no cutting out, all seems good.
Top tip!
Part from porsche -- 175
Part direct from factory in Germany --75,

Happy teddy!!
