Back in January I had a similar problem with jumping gauges, dead gauges, eventually trans stopped engaging manual shifting worked. New trans new computer, thought it was done with.

I’ve been daily driving it since then no problems. Suddenly I go to start it in a parking lot after sitting for 10 mins and rpm gauge keeps dropping to 0 and back to idle, as all other gauges are consistently twitching, charge is 14v. Start driving and sounds almost like misfire or slip Every couple seconds loosing power. speedometer twitching jumping to 60 pinned and back to 0. This only lasted maybe 3 minutes made it home no problems I will be reading codes shortly later today. Any ideas?
