I need some help. I own a 1997 Ranger and the check engine light fluctuates on and off. i recently ran codes on my truck and it showed the code 1506. I looked at my Haynes manual and it said it was the IAC Valve. so i need to know how to clean this and any other information that i will need to have before doing this.
Engine Specs: 2.3L; 4 Cylinder
