Hi all! I'm new here, thanks for taking me in, happy to see a community like this! I have some problems that I couldn't overcome with the google+chatgpt+youtube trinity so far. I have a 1989 E12 Libero, KJ8 engine code, carbed. Can anyone point me in the direction of this part? I am looking for a replacement. I managed to work out that its a vacuum switch/solenoid, but I cannot find the part on amayama or other sites. Searching for brand name/numbers was not successful either. I might see some glue residue inside from previous repair attempt, but the holes are so small that I'm not sure. According to the vacuum diagram it is connected to 2 ports on the carb, marked with "E" & "S" on the switch there are to marks, "S" & "N" If I connect this to the vacuum port to the carb as it is shown on the vacuum diagram, it kills the engine for 0.5 second in every 1 second, as soon as the vacuum reaches to a point where it is supposed to work. Basically making it undriveable at 2000rpm. If I disconnect, engine seems to misfire at every rpm slightly, not bad, but not driveable on the long run. The previous attempt was to keep the switch's electric plug connected, but the 2 vacuum ports were disconnected from it, and simply plugged into each other, making constant conncention between the to ports of the carb. I am thinking about replacing to some random "EVAP Evaporative Emissions Vacuum Solenoid Switching Valve" as I found they work in a similar mater, and give it a go. Any ideas or help is much appreciated! Thanks!
