The problem only occurs when the engine is thouroughly warm. After 10 minutes rest the fault disapears until the next time.
The m20 only has the single sensor for engine position which I assume is used to determine when to fire the injectors and spark. Without a signal the injection will stop as its the only indication that its running. Or am I wrong?
There does seem to be some history (google) of hall effect sensors becoming fa ulty when they get hot -which is why I decided to change it. I think the sensor has some simple electronics as well as the hall effect device. A single transistor I understand which can be affected by heat.
Anyway we will see... (Assuming last wednesday isnt the only warm day of the year.....)
Cheers, Robin
