Started to notice even after replacing the fuel filter, there was a very low idle, come to find out, all of the grounds were crummy, even worse, i didnt know that the factory grounding wires were cheesy little braided bands! so i replaced them all with some grounding kits i had left over from old VW's, sanded down the factory locations on the frames, clipping on new ring connectors, and put new terminals on the battery. i also shortened quite a few of the factory grounds just for better self satisfaction, no more dim lights when the ac fan comes on, and a super strong idle!
