    Default Consequences of disconnecting ISCV on 4agze

    Hi,

    I was wondering if anyone knows what the ECU will do an a 4agze if the ISCV is disconnected/removed and plugged up.

    What have you guys been smoking?

    BTW, I've D'C'd the ISCV and the car idles fine at 1500rpm (air bleed adjustment to be done yet).

    try bringing the idle down to a sensible 900 rpms or so and tell me if it idles with a fluctuation less then 100 rpms..

    if that is possible please tell me how it's possible.. otherwise i'd think that disconnecting the iscv makes it sound like u've got very big cams and will not idle properly.. ?

    As you may already have worked out, running no ISCV will not do anything bad (maybe stock ECU will throw a code though). You'll just need to adjust the manual idle bypass up a bit so it doesn't stall cold. Or get good at heel and toeing so you can keep it running as you pull up to lights.

    I need a working 4AGE bottom end. Pref smallport GZE, but all others considered. Also complete motors.
