    E36 Low Idle 500-550Rpm??

    My e36 320i starts up fine and idle's at around 750 rpm for a few minutes then after a while drops to around 500-550prm,It doesnt sound rough but not as sweet as it should and has a slight shake to it,also every now and again it will seem to miss a beat,,This all goes away at the touch of the accelorator and it drives fine.Am I just been fussy or is there a Problem?

    Is there a way to adjust the Idle at all?

    clean the ICV!! (idle control valve), if you haven't already..

    you say it goes away after you touch the accelerator so that is what leads me to believe the ICV is the only problem.. otherwise if the problem persists all the time it could be a vacuum leak

    ^^ Really old picture.

    Will this solution solve my 1.5k idle surges when my engine is cold? (it like revs by itself when starting in the cold). This doesnt happen in warmer temps though, but also does this where it will be around 700 and then drops to 500.

    As soon as you get done cranking, it shoots up to 1500-2000+? This is normal.

    Run injector cleaner. Spark plugs? Clean your idle control valve, if you have a ultrasonic cleaner that would be best. Make sure your pcv hose is free of sludge.
