Hello. I have a Jeep Laredo Grand Cherokee 2004, 4.0 Engine. The Engine light is on, did the 3X's turn on and off instrument panel, got P0505 code. I have noticed before this came up, at start up, engine would start hard but did and ran rough for a few seconds, other times high idle. Suggestions on what I should do? Not sure where the location of the IACV-AAC VALVE is located, but would be willing to replace this if this is suggested? Again you thought?

The Idle Control Valve it's probably the most common problem for the P0505 code. The valve (motor) is attached to the throttle body. The price is around $130.
