When I turn on my car the rpm goes up to 2 and stays there until I warm it up. Any reason why? HELP?

Question

It is a new car and I have no Idea why it does that but it really concerns me.

Answer 1

every newer car does that, it is like an automatic choke. In the old days you had to pull it on manually and then push it back to turn it off.

Answer 2

If it's really cold where you live that's the computer telling the fuel injectors to act like your choke is on. If it goes down to a reasonable rpm after a few minutes I wouldn't worry about it. The only thing that could be wrong in my mind is maybe the TPS Throttle position sensor my be defective. Other than that your should be ok.
Back in the day of carburated engines they had a thing called a choke to richen the fuel mixture to warm the car up. You used to have to depress the throttle and let off real quick to disengage it after it was warmed up or the car would have a really high rpm for a while. If it kept driving and got completely warm it would start to run bad because the fuel mixture was too rich and would start flooding out the car. Just take it back to where you bought the car from and ask the mechanic if that is normal for your car.
You didn't tell us what kind of car it is..... So we mechanics can't tell you if it's typical for your make and model to do that

Answer 3

It should idle somewhat higher than normal when cold, but 2000 rpm seems a little high. Could be IAC (idle air control) valve, ACT
(air charge temp) sensor or several other things. Best to have your cars OBDII (on board diagnostics) hooked up to a scanner. If you have a Autozone around they will do it for free.

Answer 4

Is it an old car? If the engine is cold it may do this. Also if the car is carborated but only when the engine is not warmed up. If it is carborated then its normal. If its fuel injected it shouldn't do this.

Hope this helps

Answer 5

It would concern me too. It sounds like it needs servicing.
