Do I need a new IAC valve

[Frdmyr]

My check engine light came on, had it diagnosed said it was bank1 sensor2 o2 sensor. Changed that light never went out, went to get emissions they said it had a leak on an elbow, they changed that and the check engine light went off now when I drive it, it idles rough and will stall out while driving. Someone told me it could be my IAC valve, my check engine light is still off, so not sure what it could be. Have checked for loose vacuum lines but found none.

You could try to remove the IAC and clean it and reinstall and see if that helps.

Yes I am going to try that first, thanks didn't know I could clean it until I read it on here.
