[DML] Frequency Valve operation

["stainlessilusion" <5n-@xxxxxxx>]

Fine tuning the engine today, noticed that the frequency valve will 
not operate unless the CO adjustment is turned CCW-lean,. FV will
then 
cycle on for about 4 seconds-fade off for a few seconds, and then
back 
on. The engine runs rough compared to turning the screw a bit towards 
rich-it will then run smooth which is how I'm running it now-but the 
FV isn't on. After a little while I'll start the car and the FV will 
cycle (causing a major hunt in idle), but after the engine warms up
it 
will shut off and not come back on at all. Bad O2 sensor? -----Dani
