My 2001 Nissan Pathfinder's Idle is going up and down 1100 to 3000?

I'm in the same boat with my 01 Pathfinder and the most likely answer is the Idle Air Control Valve or IACV. The question we haven't solved is why the valve isn't working. By all accounts the IACV is a very solid part on the Pathfinder. The dealership wants me to replace the valve and possibly the ECM also. The valve is about $400 but the ECM is closer to $1300. A second shop said the problem was wiring. I don't have the final answer but would like to hear any feedback you have
