Do you want the RPMs to be low or high?
You want the RPMs as low as possible as it truly is RPMs that really burn fuel (frictional losses with higher RPMs). However, if the RPMs are too low, then you don’t get the benefit of timing advance… So, “it depends” on naturally aspirated manuals.
What makes a car not accelerate but RPMs go up?
1 Fuel Filter. If the gasoline in your car isn’t pure and clean, there is no way your engine will work effectively. 2 Exhaust Filters. If any of your exhaust filters is clogged or blocked, you may experience a problem while driving. 3 Cylinder Compression. 4 Air Filter. 5 Camshaft Sensor. …
How to monitor RPMs to get the best performance?
When you need to slow down in a vehicle with a manual transmission, you can monitor the RPMs to determine when to smoothly downshift to a lower gear. Press the clutch in and rev the engine to the engine speed at which you would normally shift to a lower gear. Shift to the next lowest gear, then slowly let the clutch out to engage the gear.
Why is it important to know the RPM of your car?
For this reason, tachometers or RPM gauges are used in cars to track the RPM. Knowing your engine RPMs is important to: Drive your vehicle without damaging the engine. Tachometers or RPM gauges indicate the RPM as a multiple of 1,000.
What’s the difference between rpm rev and no acceleration?
RPM rev and no acceleration? I have a 2004 Hyundai Sonata with about 85,000 miles. For the past few weeks, when trying to accelerate, I press down steady on the gas pedal, and sometimes the car does not accelerate. Also, the RPMs rev very high from about 2 to sometimes 5,000 (all with no acceleration).

Why is my car revving at high RPMs?
But, to answer your question… No, a clogged fuel filter would not explain an engine that is revving at high RPMs without the car moving at an appropriate speed. The most likely explanation would be a failing transmission if it is of the automatic variety, or a slipping clutch if it has a manual transmission.
Why does my car not accelerate uphill?
We also showed you the main reason why car won’t accelerate past 40 and also why car wont accelerate past 20 and finally, we discussed the reason your car wont accelerate uphill. So if your car won’t accelerate but RPMs go up automatic then you know why that is so.
