The engine DOES have an air flow position SENSOR & it will cause erratic idle problems as "suginami" has suggested!!

There are 4 sensors that inform the computer how to adust the idle speed. Throttle valve switch, decell switch, hall effect speed sensor, & the air flow position SENSOR. OF course there are other imputs to the ECU but they don't have much effect on idle speed.
