I recently started working on my car again, and got some more strange running results.. Before, when the key was turned to the 'on' position, the frequency valve would buzz and buzz and not stop. NOW, it's buzzing for about a second, and stopping. What is it supposed to do? If it's supposed to keep buzzing, does anyone guess why mine is not? I've been fighting with another problem- running rich. I just recently found that 4 of my vaccuum lines were hooked up incorrectly- the fuel pressure regulator was hooked (at the T) to the manifold, the hose the regulator should be hooked to was connected to the distributor's spark advance, and the other two hoses coming out from under the air intake were connected to the solenoid. Who would have created this debauchery!!? Also the power to the pressure regulator was disconnected. having hooked that all back up, it still runs as bad as ever... billowing black smoke comes out the exhaust.. If the frequency valve is not working while running (can't tell, there's only one of me and the car won't idle at all), could it cause the car to run so rich? thanks for the help... Jim
