On the right plug you see a yellow wire and a pink wire by the ignition coil. I noticed my yellow wire was shorted with electrical tape. My question is was this wire originally fastend to the block ? My truck will sometimes die when I put it in gear but much less so now that I have a new distributor ignition coil feud pump and started. I’ve had to adjust my idle screw clockwise to make it run better at idle. It feels 90% good just not sure what to do with the yellow wire coming off of the plug . Apparently it’s for the EST circuit and the yellow wire is a ground wire? If so where should I mount it
