Being a fuel injected engine , there are many reasons this could be happening.
from the top , lets check the Manifold Absolute Pressure (M.A.P.) sensor , as it is easiest.
Find the MAP sensor , it has a couple a wires and a vacuum tube going to it and is on the firewall or fender support under the bonnet.
Disconnect the wire harness from it (small plug with wires).
If the engines RPMs drop to normal , replace the MAP sensor.

1997 acura cl 2.2 revs up to 1500 rpm and down to 1000 rpm just several seconds after start


Cars are design to run at a higher idle at start up to warm them up quick. There is a sensor that reads water temperature and tells your car's computer how fast to idle. Your RPMs seem slightly high but not out of the norm. Does idle ever drop to around 600/800 after about a minute? If not, your engine temperature sensor maybe defective.

98 explorer 4.0 SOHC wont idle and stalls when weather is below 40 degrees. worse when colder. Just had tune up, new airfilter new fuel filter but problem did not get better.


you have a bad idle air control valve. its job is to have motor rpm high until the motor warms up then turn it back to normal.

Engine idles up and down radicaly when first cranked , check engine light is on auto-zone put their reader on truck and it pulled up code for mass air flow sensor, so i replaced it still no change.


your idle is compensating for poss air leak like vac or idle air motor,does it settle down as it warms up .if so then a poss coolant sensor is thinking that it is 50 below.hence a very rich mixture and a idle which will hunt.idle air motor maybe plugged with carbon.also disconect the battery for couple of mins.start and hold idle high about 2000 rpm for 5 mins if all above does not work.

Rev count for 2009 corolla pro. goes up when engine starts even when the car is not moving. Is that normal?


High idle indicates that the engine most likely has a vacuum leak. This could be due to many causes; cracked hose or hoses, bad gaskets..ect. Hard to say exactly without more info, but you can open the hood and inspect the vacuum lines for damage or cracks. It is a 2009, so it probably is not something major.
