It's mounted in the throttle body..

Is your car having idle problems by any chance? The IAC valve could be stuck in position if the PCM is messed up. If the IAC valve is retracted, rpms will be high and if it is stuck closed it may idle low.

per previous post, it's behind the t/b facing the firewall. it is held on by two bolts and has two small coolant lines connecting to it.

since the zc is pre-obd and jdm, your evap purge solenoid connector is probably going unused. make sure it didn't accidentally get plugged in to your iacv. the connectors are identical and easy to mix up. i know from experience.

if everything is connected correctly, try removing it and cleaning the screen. last resort would be to try a known good iacv.

okay will unhook the the iacv and reset the ecu and see if it throws the same code?
