- It is very important to calibrate the IAC valve after cleaning and lubricating it to allow the engine revolutions to settle at a fixed value.
If the IAC or idle valve has not been calibrated correctly then the engine will have increases in RPMs (engine accelerated at idle), ups and downs in idle revolutions and even the engine will shut down a few seconds after starting.
IAC valve calibration involves two steps: mechanical calibration of the air control cone and electronic calibration.
