Why is my RPM revving 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.
Why does my car rev to 2000 when I start it?

What causes a motor to rev high?
A slipping clutch will cause the engine to rev higher as the transmission struggles to work correctly. If your clutch is slipping, the clutch pedal will take much less pressure to engage. A slipping clutch will also cause your vehicle to lose power and struggle to stay up to speed.
Does high RPM hurt engine?
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
Why does my car rev up but not accelerate?
Transmission slipping, or gears slipping, is a common transmission problem and a real cause for concern. If your engine revs up as you press down on the accelerator but your vehicle doesn’t accelerate as per usual or as you would expect, it’s a troublesome sign that can lead to a full-blown transmission failure.
Can bad spark plugs cause high RPMs?
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds.
What should RPMs be at 70 mph?

What was the hesitation problem on my Subaru Outback?
