I am not knowledgable enough to know if this is correct but here is my best reasoning. Its actually a guess.

When mesuring the frequency valve using a dwell metter I get a steady solid 45 degrees without the O2 sensor conected. This is normal and is the default when the O2 sensor is disconected. With the O2 sensor conected the dwell metter reading fluctuates 42 to 48 degrees. It is causing a fluctuation in the idle. About 50-100 RPM. I can feel it at low speed. Also the air/fuel metter goes leaner than it should. If my guess is correct the signal to the frequency valve is bad. The signal is something like 10 pluses per second. Is it possible that one wire trigers the plus and one wire is conected to the timing circut. Could then the difference between between the two signals confuse the frequency valve?
