I have never heard of a priority stop. I don't have a silver bullet for your situation, but here are a couple of things I would do now: If you can get that car in a really dark place, look for something that glows. Make sure to check the glove box courtesy light and the vanity lights on back of the sun visors.Another thing to do is try touching all the relays and all the modules, radio amps, etc. you can find-even better would be to use an electronic non-contact thermometer and with either method, look for anything warmer than the it's surroundings. The last thing I can think of to suggest is, with your ampmeter showing that 100 or 140 ma draw, start unplugging relays. Remember when you're inside the car to trip the door latches; ditto the hood or trunk latches. Oh, I almost forgot-anything on that car that isn't stock is suspicious. Aftermarket stereos and anything plugged into the cigarette lighters deserve some attention. Sorry about all the generic advice, but I'm short on specifics on your car. I do hope you'll post when you get it figured out.
