So i am in the process of doing mechie's gauge change tutorial(changing the green wrx gauges to blue). Everything looks pretty good, except now when i plug the gauges back in, the needles dont act the same way. The tach and speedo work, but they are really jerky. The temp gauge stays on cold, no matter how long i drive. The fuel gauge is stuck on E even though there is a full tank of gas.
The gauges definitly have power, they just arent working the way that they used to. When i was doing the entire process, i never really messed with the needles. I didnt pop them out or anything, and now they arent acting the same way. Someone sugested that they will eventually "wake up" and fix themselves the more i drive.

Any help is appreciated.
