Fellow Q-Listers, I need to know what the frequency valve on my '84 Coupe GT does. Mine is not running. How big of a problem is this? I believe that I may be missing a relay. Could this stop the Frequency valve from operating? Also I would like to thank the person who sent me the articles I was looking for, (I lost your e-mail so I can't respond directly) Thanks in advance for any help Jeremiah Curry
