What causes RPMs to drop slowly?
However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is failing, your vehicle will stall instead of slowing to an idle after the release of the throttle.
When do car RPMs go up or down?
The RPMs did not go above 3000. The RPMs also got a shaky and moved back a forth a bit. On the highway the car slowly got up to 45 MPH and 3500 RPM, then it was stuck there for about 15 seconds – it would not go any faster and RPMs would not go higher. After those 15 seconds it finally went above 3500 and got up to 60.

There might be a leaking vacuum hose in the car, hoses deliver air and fuel to the combustion chamber. If it is leaking, the air will mix with the gas causing the RPMs to go higher than it should be. Another thing to look out for is a clogged air filter if the air is having difficulties entering the combustion chamber.
What are the slow accleration and moving RPMs of a car?
I turned around and pushed the gas pedal to the floor and car never made it above 25 MPH in about a quarter mile. The RPMs fluttered a bit, between 2000 RPM and 3200 RPM with the gas pushed down all the way. I parked the car and there were some strange smells. I am not sure how to describe them, at one point almost the burning rubber.
