Question s10 4.3L Diagnostic- No speedo/gas/temp guage

Hey everyone, about a month ago I replaced the ignition switch in my 2003 s10 because the vehicle would sometimes not start. I would put key in and there would be no power to anything, even the horn didn't work. Turning the key to the start position did absolutely nothing and as mentioned above nothing was powered.

I put in a new ignition switch which solved the starting issue, fires up every time now. However, now half my gauges are not working while the car is running. With the key in and turned ready to start the car, everything works. However immediately after it is running the gear indicator goes out (automatic), as well as the gas gauge, temp gauge, and having no speedo. Occasionally while driving all the gauges will start working correctly, firstly with all the warnings lighting up, and after ~5 seconds, it will be back to how it should be.

Lastly, when the gauges are not working after I start it up and I shift it into drive or reverse, it is a violent shift where the car will lurch. The car never does this when the gauges work after start up. (Gauges work roughly 5% of the time from start up, and of that 5%, gauges will go out while driving half the time.

What are your thoughts?

I would go back and look at your ignition switch replacement, check the connection to the switch for bent contacts or a chaffed wire.
