bellhousing sensors

[Mr.SWISS]

My eta has this issue after a bit where it stumbles and loses power but return to normal with a quick restart....

I replaced the AFM and the TPS but I am starting to think the issue is injector timing being off. I have read one is a cam/reference sensor and other is CPS. What's the function of the one on the front pulley then? another TDC sensor?

Plz explain these sensors roles....

All engine timing functions on this car are via the bellhousing sensors. The sensor on the front of the engine is only for diagnostic purposes and only connect to the diagnostic socket.

[Mr.SWISS]

does this pin in the fly that likes to come out cause the CPS to lose it's mark or is it the cam/reference sensor pin? Or is there one for each sensor or shared?
