alright few days ago when i started my car it was fine, but somehow after i start the car the rpm is idling at 2500 ? but after driving the car idles back to 1000... does anyone know why its doing that?

 

I believe that's perfectly normal to operate idle at higher RPMS until warm, then it should drop to around 850ish.

 

It will idle high when the engine is dead cold, then settle down as it warms up. Sounds normal to me.

 

does this typically happen in the morning or after the car has been sitting for a long time?
If so, it's pretty normal. Our car idles much higher then normal when it's cold and after a little while the idle will drop down to it's normal range.

edit: holy crap you guys are fast...

 

it happens after school most of time after siting in the sun for hours..but not in the morning

wow you guys all replied 3 min after my post!lol

 

buncha forum ******

sounds normal to me

 

okay good,
thanks

 

Im pretty sure that when you start a car, it idles high, and after a few minutes (warming up), it goes down to 1k or so .. thats just me

 

The girls don't call me the 3 min man for nothing. wait a second..........

 

this is the same for every single fuel injected car.. nothing new.. wtf.

 

They have been doing this for many years *The RX-7's of the 80's did the same thing!*. It's there to help warm up the car.
