[V8] Hall sensor

[lyddall at netzero.com]

Still having a problem with the hall sensor - this started out as a steering rack replacement 2 weeks ago and is now getting frustrating.  In the process of replacing the rack I broke the hall sensor connector on the distributor.  I didn't realise that the plastic cover over the wires inside the distributor also disintegrated and then managed to get jammed between the rotor and the cap.  So - I replaced the distributor, and still have a rough running problem.  It idles, but is lumpy and hesitates when you push the gas.  If you actually try driving the car it struggles to shudders.

The code is 2113 - Faulty hall sensor.  I did the checks as described in the manual, the voltage seems right on pins 1 & 2, and there is a blink on every complete turn of the rotor.  That was one thing I wondered about - the book says "should flash briefly at every second engine revolution".  Does anyone know if the book is right?  I'm not sure how it would only flash every second revolution, given that it flashes whenever the opening in the hood goes past the sensor.

The other theory I have is that when the pieces got jammed in the distributor it somehow made the toothed pulley on the front of the cam slip so that the cam is now slightly misaligned.  I hope this is not the problem!  Can you check TDC on the distributors?

Any suggestions appreciated.

Dave
