    RPM's stay up after i put it in neutral??

    hey guys,

    i noticed that at the dragstrip and doing pulls,when i push my clutch in,put it into neutral,the RPM's stay high.Then after a couple seconds,they drop.is this normal?I have a ACT HDSS clutch(not pucked) and RRE light flywheel.

    For example.,when i was at the track,shifting at 7k rpm's,after 3rd gear i pop it into neutral,then it hovers at around 4k rpm's,then after about 5 seconds,it'll slowly go down.

    thanks in advance O0

    Idle air control valve...

    It happens on all Evos under certain conditions... nothing to be alarmed about. I havent been with the IN crowd as far as tuning so im not sure if there is some type of fix for it yet.. last time i checked u just have to live with it...

    ooh ok.so its nothing to be TOO concerned about?when i had my stock clutch and stock flywheel,it never happened to me.i was thinking it had to do something with the liteweight flywheel.


    thanks for the response!!!!!!

    so we should just replace the IAC if we should face this?

    no not necissarily. and come to think of it i didnt even replace mine(it was another part), i cleaned my tb and the control valve thouroghly along with triple checking all vacuum lines and it rid me of the problem :twisted: :mitsu:
