Hi all....my goat is doing something kinda funky.... When slowing down to a stop, say, coming up to a stoplight, when the engine is almost back down to idling speed there's a click and for just a split second, it almost sounds as if it will stall. It's more noticeable at night only because you can see it in the headlights. They dim briefly. You can hear it in the stereo too. Watching the tach, there's a split second drop in rpm's, all the way to 0. It's very quick and very brief, but it does it every time. Anyone else experienced this?
