RE: [DML] Re: Engine Trouble

Joe, As I said I have seen the FV not work and when the 02 was replaced it
started the BuZZZ again. Your mistaken because I had the car here last year.
The man is looking for answer not so much for in-depth technical that he
can't possibility control or even fix and doesn't have the dwell meter to
measure with.
The FV won't do it's job of varying the pressure on the lower chamber of the
fuel distributor if the 02 / ECU isn't ( working )correctly.
Yes, It as I know will sit in the manuel state of 80/20 and the car will run
rich, thus causing a problem.

Not so. (See workshop manual D:04:10 System Control Monitors, bottom
of page) In other words if you disconnect the O2 sensor or short
circuit the sensor lead the Lamda ECU will continue to send a fixed
voltage to the frequency valve resulting in continued operation. Most
non-working frequency valve conditions are related to circuitry
problems. i.e. A broken wire, connector problem, or defective
component. Refer to D:04:12 items #1, 2, and 3 to locate the source
of the problem.
