RE: [DML] The FV

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Josh, Until the 02 sensor heats up from the exhaust and starts sending a
voltage to the ECU, the car is running on a fixed air to fuel mixture ratio.
Then when the 02 sensor / engine heats up to it's normal operating temp. is
the time to adjust the mixture screw to correct the seeking.
The air to fuel mixture is either rich or to lean and the adjustment needs
to be done to bring it back into sink. I would suggest you do this after you
have installed a new 02 sensor and adjust this is when the car is hot. If
any questions your welcome to call 12/7.

Guys I just had a quick question about the frequency valve if anyone
can help me out. My engine idles fine when I hear the FV running, it
is the  distinct sound you can tell its running. Then it suddenly
cycles off and my engine idles a bit worse and starts to idle up and
down for a little while until the FV starts back up again. Problems
with the wiring or is this normal? Thanks for past and future help!!
