Right now I have been running rich almost randomly. The problem would come and go every few months and I would lose some performance. I found after moving my lengthened MAF ground wire the engine would return to normal. However I've replaced as much wire as I could before the wires lead to the huge wire bundle. I think there may be a break inside the insulation further down the wire that I can't get to. Would it work if i took my MAF ground wire and put a wire right to the battery ground? Is there any danger doing this?
