P1011 Code on 2001 V70 V70-XC70 2001

My daily driver is a 2001 V70 non-turbo (B5244S) with manual trans. It now has 220,000+ miles, and recently showed a CEL, started to hunt-at-idle, and periodically surge briefly (like I hit the gas momentarily when I hadn't) at low speeds. I read a lot about the ETM issue, and decided to go for the XemodeX swap out. The old ETM was original (white label with wires running behind starter)which was surprising, so I thought that it was surely my problem. The new ETM hasn't been in for long, but I still get some hunting-at-idle, although not as large of a fluctuation, and not as often. The CEL light is still on, and scanning shows a P1011 code. I'm curious if anyone knows what the code is, and could this also be the cause of my idle issue?

All thoughts are appreciated.

Regards,
Porter

    I really dislike the P1nnn or P2nnn codes because they mean different things to different manufacturers. I came across 2 items for the P1011:

    For engine code B5254S, P1011 = ECM-7110 = Engine control module, internal fault in knock sensor circuit.

    Faulty reading for MAF sensor.

    Neither of those two sound good to me. Your best bet is to get a scan with a Volvo scan tool for pinpoint accuracy.
