Also test your TPS (Throttle Position Sensor).

I already clean the IAC and the TPS. Theres any value I can check out with a Multimeter, before I discard the IAC or the TPS or both ??
In PARK position idles normally, the irregular RPM appears in DRIVE position. Thanks for your time.-

Testing the TPS is not difficult. Lots of good videos on YouTube.
