that sounds very familiar. I have spent the last 11 months trying to solve the same problem (with the purchase of a new car in between, not long after the HG went on that to so I swapped engines, still had problem).

Anyway, in my case it turned out to be the cam wheel wasn't stragiht on the shaft, and the sensor was fouling it on one side and too far on the other.

Remove your passengers side cam belt cover, run the engine and have a look at the cam wheel, if it oscilates back and forth in relation to the sensor then that is most likely your problem.

If that's it and it fixes the problem, thats 11 months of hassle for me, you owe me

good luck.
