I have installed all new relays in my car after trying to unsuccessfully replace the 555 timer in the original RPM relay. Now when my car runs the RPM and Lamda relays click constantly about every second. The car seems to run and idle fine but I know this clicking isn't right. When I checked the engine for anything unusual I can hear what I believe is the frequency valve sounding a constant buzzing. I tried adjusting the fuel mixture screw but that didn't seem to make any difference. Does anyone have any ideas on what might be wrong?
