I finally got my car back from the shop and was looking under the hood and I found a cut wire. it is blue and yellow located next to the resistor box. when I hooked it up again the car idled faster, guy at shop(NEVER going there again by the way) said he adjusted my idle. ECU shows code for IACV so I have no idea how he adjusted it basically wasting my money on useless labor. so just wondering what this wire is and what it's for, I am waiting on an igniter from e-bay so if this fried the first one I dont want to keep fixing shit, thanks.
