Re: frequency valve again

[dherv10@xxxx]

Jim, The FV pulse ratio is controlled by the Lambda unit and the 02 
sensor after the warm up and the thermal switch has been enabled. If 
what your saying about the vaccuum hoses is correct, then the 02 has 
probably been contaminated beyond repair and needs to be replaced.The 
FV should be running at idle to lessen the fuel pressure in the lower 
chamber to run leaner. But: is the engine hot or cold. If it's cold 
it's going to run rich. Crank it up and go out and drive it till it 
gets hot. Then listen to the FV and maby some of the contaminates may 
burn off the 02.
