Why do the RPMs fluctuate on their own without hitting the accelerator?

I am having a similar problem with my 95' w/351. Mine fluctuates by about 300 rpm's and is fairly consistant every 3-5 seconds. I've been told that it is a vacuum leak, however, I've replaced just about all of my vacuum lines. You cant buy the factory hard plastic tubing, so I fabricated my own out of aluminum tubing and a cheap tubing bender. The aluminum tubing is readily available from hobby stores and is fairly inexpensive. Hope this helps you out. I cant find anymore vacuum leaks on mine, but it still fluctuates. Jon

What is the problem with a 1998 911 Carrera if the RPMs are revving up unusually high when you hit the accelerator?
Perhaps you have not engaged the clutch? The accelerator is designed to increase the RPMs. If you provide no resistance it will rev until it explodes.
Will spark plug gap causes a RPM gauge to go up and down while idling?
The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.
What would cause a 91 standard transmission Tracker to idle fast 3000 rpms at start up and then fluctuate in rpms 1000 to 2500 after the engine gets warm?
The first thing it sounds like is a vacuum. if not, check timing.
What makes an automatic transmission change down when the accelerator is depressed?
When you press the accelerator, the engine wants to tach up right then and there... in the current gear the car is traveling in, it may not be possible without bogging the engine down, so the transmission is shifted down in order to accommodate the demand for increased RPMs while preventing the engine from bogging.
Why would the RPMs fluctuate when stopped at a light in a 2000 Galant?
The idle control solonoid probably needs cleaning. Remove it from the throtle body and clean it.
What will vehicle speed without accelerator in first gear?
Well, an exact number will depends on your RPMs at idle, the gear ratio of that first gear, the gear ratio of your rear end gear, and tire size. Generally, five MPH or less.
92 Toyota Corolla the Idle speed suddenly jumped from 1000 to 2500 rpms when put into park you adjusted the idle screw as much as possible. got it to 1800 rpms. What else can be done?
Check the timing and check that the cable to the accelerator is adjusted correctly.
When you push the accelerator down all the way on a automatic 1999 rodeo it sometimes changes to the next gear at 4500 rpms and sometimes at 5800 rpms?
Depends on position of power switch in the console by the shifter....Also depends on vehicle speed and gear you are going into
How fast does a 2006 GMC Sierra go?
ive had my 2006 gmc dually 3500 up to 135 mph hitting 2500 rpms
Why is the rpm fluctuates but the transmission is shifting fine on my Honda Accord?
A fuel pump that is not functioning properly will cause the RPMs to fluctuate. The fuel pump may be going bad, or it may not be grounded properly.
What makes a car accelerate?
The more you push on the accelerator the more you increase the fuel/air mixture to the engine which will cause the engine to turn more RPMs, thus propelling the vehicle at a faster speed.
How do you shift 13speed truck trailer?
There are eight actual shifting motions, and you can "split" the top four gears. Get to your desired RPMs before upshifting, then you can either float or double clutch into the next gear. For the splitter, you simply push it forward, let off the accelerator, pause until you feel it catch, then get back on the accelerator.
