Start by making sure the BISS is adjusted correctly. If it's not, the IACV may have trouble keeping up.

EvoScan will tell you what the IACV trims are. If you can't log data, I think there is a way to kinda do it by setting idle with the IACV unplugged.
Also, check for vacuum leaks.

A search on this site should bring up a number of threads. I'm 99% sure I've seen a few on how to do it.
