my cel came on with a code 14 (IACV). I have not done anything to my car for about a year (other than regular maint.) except two days ago I recently created a ram air style intake. today the code came on and I checked my IAC Valve and it was fine. So I relocated the ram air scoop, reset my ecu, and now the light stays off. I have a d16y7 with engine mods limmited to my custom intake (too poor to buy a real one). I really don't think an intake would cause this but can not find anything else wrong. Any input will help.
