2005 Pontiac Sunfire RPM Guage

My RPM Guage while the car is off is sitting at 4k. When I turn on the car and start moving it only goes up from there, it actually runs into the speed guage. Is it possible to reset the RPM Guage?
Do you
have the same problem?

I have the same problem with my car, the same as yours but mine is an automatic. I took mine into the dealership and the mechanic said it was either the acceleration sensor or the cluster something or other behind the gauges in the dashboard. The sensor part will cost you over $200 and the cluster thing will cost over $350. And that's just for the parts. Labor is more than double that.
As for "resetting" the RPM gauge, the only way that I know how to do that is to "bump" the ignition switch. Start with your car turned off. Turn your switch almost to the point of engaging the starter but don't engage it. The closer you can get to actually engaging the starter the better, just don't actually engage it. (If you do engage the starter and in turn start your car, you'll need to turn it back off because the rest of this won't work if the car is running.) And then let the key go back to the "run" position. This will cause all of the gauges on the dashboard to sort of "twitch", which in turn causes the RPM gauge to "twitch" bake to zero. With my car, when the RPM gauge is "stuck" at a high number, each "twitch" of the needle will drop it about a half k on the gauge, from 4k to 3.5k and so on. You'll need to repeat the ignition switch bump several times to get the gauge back to zero. Just in case you don't already know, your gauge will tend to act up more when the weather is really cold or when it's been raining pretty hard for long periods.
