My odyssey check engine light went on and we got the code po505 Idle Control Malfunction..no other codes came up.

The idle jumps up and down, but other than that I haven't noticed anything else wrong.

The TCS light comes on and off when the check engine light comes on...I don't know what to think about that.

Would replacing the IACV fix this problem or are there other things we should do first. Any information you have would be very helpful! Thanks

You can try cleaning the IACV before replacing it. That may save you some money. A lot of times, carbon build ups prevents the pintle from moving in and out freely.
