Good to know, thanks for the information! Now that I think about it, I wonder if the ELD being unplugged could be affecting the idle RPM while coasting. I'll have to try plugging it back in and see if that makes any difference.
Something else interesting is that the ECU has not set a code for any IACV or idle speed issues, which would seem to suggest that it is getting it's way with the idle speed. I know from experience that these cars will set codes if the idle is high and the ECU can not bring it back down to normal for whatever reason. Maybe the high idle while coasting is just how these cars are.
