    Question d16 turbo high idle

    if i make any kinda of boost my car will idle around 1500 rpm i think it has to do with the map sensor but how to i solve this problem plus i think it sends it into a safe mode and if i turn the car off and restart it it idle's normal

    idle wouldnt be affected by the map sensor, its most likely your iacv or cold idle valve

    a little more info on your setup is required.
    1. what engine management are you using (stock inj fmu missing link, 450cc afc hack, larger inj w/ tuneable ecu)?
    2. what d16 do you have?
    3. any cel?
    4. how much deflection is on your throttle cable (none, 1/8", 1/4")?
    5. what throttlebody are you using?
    any other info you have will help in the e-diagnosis...more is better than not enough.
