What causes rpms to jump while driving?
If your RPM fluctuates while accelerating, it could be because your spark plugs have gone bad on you. Worn-out spark plugs can cause misfires to occur within your engine, and those misfires can lead to your engine vibrating a whole lot. Those vibrations can lead to the RPM in your engine going haywire on you.
What would cause a car RPM to stutter at high speeds?

Do you shift at 3000 rpm?
If you’re accelerating normally then shift at the lower end of that range — 2000 to 2500 rpms is usually appropriate. If you are accelerating faster then maybe 3000 rpms is a good shift point. Accelerating very fast, pick your shift point. Just don’t exceed the rpm red line.
Can you shift at 3000 rpm?
The typical “rule of thumb” with shifting is that when you reach around 3,000 RPM it’s safe, and desirable, to shift. Of course, shift any sooner than reaching 1,500 RPM and it’s safe to say you’ll stall out.
