Dave, Take me or someone up on replacing it to see if it's the problem, make sure the 02 sensor is good. If the FV isn't working then your gas mixture will be rich.

My Frequency valve will not come on...well.. ever. Thanks to Rich A I have been able to test all the parts of the system. The car runs no differently with the Lambda ECU disconnected or the frequency valve disconnected. I'm surprised how well it runs without the Lambda system but I want this fixed.
