Having an issue with part of the instrument cluster turning off, then back on while hard acceleration. Only the Tach and Speed seem to be affected. Fuel, Temp, oil, all remain ok and no loss of power or cutting out of any other electric components like dash/radio. The Alternator has been replaced, checked the connections and appear to be good. No battery light or engine codes. My guess is it'd have to be a bad connector somewhere that vibration while accelerating is causing the issue. Anyone have a similar issue or best place to start looking.
