Why does my car only go up to 4000 rpm?
This could be from low fuel pressure, a clogged fuel filter, a clogged air filter, a faulty throttle cable, carpet blocking the throttle pedal, ignition system failures, computer problems, timing belt jumped, transmission, exhaust, and the list goes on.
What RPM should my car be at 25 mph?
That is, 63360/82.3 = 769 revolution per mile. So, if the car using this tyre is travelling at 25 mph, that wheel is spinning at 25 x 769 = 19225 revolution per hour or 320 rpm.
What does it mean when your car won’t go over 20 mph?
Misfires can be caused by many things. If you have already replaced the MAF, spark plugs, and wires then the next things I would move on to are the EGR valve and the fuel pump. If the fuel pressure runs low, due to a worn or weak fuel pump then it may cause the engine to misfire due to a lean condition.
Why does my car shift at high RPMs?
Automatic transmissions are designed to shift at different RPMs based on the amount of throttle you input. If you are accelerating quickly (with the pedal to the floor) the transmission will shift at a higher RPM than under normal driving.
Is it bad to drive at low RPM?
Low RPMs are fine if you’re just cruising or slowing down, but when you accelerate, low revs leave your engine with a gearing disadvantage. To get your car up to speed, the engine has to work a lot harder. Engine temperature will rise, and cylinder temperature will rise.

What causes car RPMs to go up but not down?
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.
