Still trying to solve the #6 cyl misfire in my 80 series. Today i was pushing/pulling the injector wires/connector while truck was idling and I could make it misfire more, or less, depending on what I was doing. I removed the connector and bent the metal contacts on the injector just a wee bit, plugged it back on and the misfire while driving is definitely better - though not entirely absent. It is better than it has been in weeks. I'm thinking it is either the connector, or the injector. Any help/suggestions will be appreciated.
