Hondata

<Problem>
Idles very high (3000rpm)
I cannot decrease idle rpm even though changing idle parameters.
I tried decreasing "Idle speed" and "Idle valve duty cycle adjustment"
When ECT is low, it idles around 1200rpm. However, once ETC gets higher, it idles up suddenly to 3000rpm.

- stock miata/ stock engine
- bought kpro4 at KPowerIndustries in this July

Best,

Most likely the IAC is stuck. Take the IAC apart and clean the vane and housing until it spins freely.

Thank you very much for the quick response.
I will try to clean IACV.
