Re: Frequency Valve

The ECU uses it to adjust the fuel/air mixture, receiving feedback from
the OXS ("lambda sensor")

should be buzzing... the duty cycle can be measured at the loose two pin
wire by the air boot - 

Wait!  You've got the super spiffy "newer" CIS.  Not like my old jalopy
(the 84 and 84 I just got, total beaters, one hasn;t run in 8 months,
both start like new cars!)

Guess I don't know how the freq valve works on that car... guess I'd
like to!  Might be similar in end result, just a fancier ECU with better
curves and computer controlled warm up (instead of Rube Goldberg
