Bad O2 sensor symptoms??

[RidingSimple]

Pulled out the cam sensor and there was fresh motor oil on it. Not a lot but enough for me to ask if its normal. I tested the sensor on the side with 3 prongs and it came very close to 1250 ohms (tested between prong one and two). I think this is the correct test procedure, but at this point i don't know. I'm getting a 1244 but the cam sensor seems fine.:confused::confused::confused:

If you have an M42 (like we all do), chances are the passenger (right) side of the timing case leaks...which, in turn gets the CPS wet with oil.  Ask me how I know. :rolleyes:

And to reiterate what Dave mentioned above, I tested faulty AFM with the stomp test when I indeed had a loose vacuum hose.  So not always 100% accurate.

I did replace the "mess under the intake". Could the hoses i have be caving in under heavy vacuum. I'm using 5/8 heater hose from the intake boot to the ICV. Not strong enough? I would like to know what hose people are using. Perhaps the hoses heat up and become softer and more likely to compress under vacuum. That may explain why this problem exists only after driving 10-15 miles.

I disconnected the battery to reset the codes (search function does work). It read 1444. I took the car out and drove it hard to see if the problem would return, it didn't. I thought that if i could get the car to cut out at 5500rpm again a code would appear, perhaps different from the first (1244). I did the stomp test once again and the code was still 1444.

Could the ECU/DME??? have remembered the past code of 1244, which would make it run as if the vac leak had not been fixed?

1244 is for cam sensor, but i guess this test is not accurate. Tell me if this even makes sense...my mind hurts.
