    idle speed

    hey guys i am now the proud owner of a 13 subaru wrx premium i live in nyc
    how long should i warm up the car before taking off?
    and when i turn it on this morning the idle was at almost 1.5k rpm is that normal? (i have a bike where the idle is at 1.4k but when cold it'll reach up to 2k rpm. what is the idle suppose to be?

    My routine:
    Start car
    Choose radio/music
    Tidy up whatever is on the passenger seat
    Put seat belt on

    Idle speed is based on coolant temp. The latest stock ROM I can find is from '09, but I'd guess your table would look similar:

    Yes its normal, mine idles around 2k when its cold. Its usually safe as soon as it drops below 1k rpms.

    Yep it's normal. You don't have to wait for your car to warm up completely. You can drive it just fine even when the idle is high. Just don't go beating on it or gunning it until it's up to operating temp. When you do start it, let it idle for a 20-30 seconds though at least to cycle oil through the engine (which is what Matt above eludes to by seatbelting, checking radio, etc.).

    I second what Mikie13 said.

    Until it's warmed up, keep both the rpms and load low. It will warm up faster if you wait 30 seconds and start driving easy.
