Car is idling low, base idle was reset at dealer about a year ago due to same problem, 5 min and 95 bucks, I read somewhere but can't remember where that it can be reset through the DLC by grounding a pin, if so which pin and where is the dlc on this car. Any help appreciated

Is the DLC under the dash or hood, are the pins numbered for easy ID or do you have a pic. Thanks

Its under the hood next to the power distribution box-it will show the pins under the cover
