My car idles really high and wont go down and it will stall if I push on the gas!!
If your vehicle has an automatic transmission with overdrive, then at speeds above 45 mph, it should be in overdrive, which reduces engine RPM's to save fuel.
How about it shifts into 4 overdrive gears are higher so RPMs come down.
Safety feature is tripped, bring in the car to a shop.
Out 2000 Dodge Neon does 2500 rpms at 60 mph. Grace
Several things it could be, but frankly, if it's that bad, get a mechanic.
Don't know what vehicle you have but that may be as fast as it was designed to go.
It depends on a the gear ratio of the transmission in high gear and the final drive rear axle ratio. Also depends on whether the car has overdrive or not. It also depends on the size tires and wheels mounted on the vehicle. All these factors will determine the rpms at 25 mph.
because you are making the motor run higher rpms therefore using more fuel.
when your vehicle is in park the rpms will rev and and down fluctuating. howver, when car is in gear it will seem to be fine. but, as problem gets worse it will shift to higher gears. for ex. when mine went out my car maintained 45 mph without doing a thing. also, when you go to slow down it will jerk because it is having trouble switching to lower gears due to air intake.
yes & no if your motor looses compression your car wont go over a limited
1800 or so
