I have this odd phase I have to go through on staring my GSL-SE. The BAC valves sound like they are shorting out for a moment then it cuts out completely. She comes back a few seconds later and I can start the thing. only to gain a rough idle at 1200rpm and gradually drops to 100rmp within about an hour. It does this everytime I start. The whole mess causes a big problem with the fouling of the plugs. Can any body explaine if there is a bad relay or a missing part, maybe. Any knowledge would be greatly appreciated. I personly havn't been able to identify anything but the horn relay, and that works just fine.
