Low RPMs bucking - ZR-1 Net Registry Forums

Update:

Removed fuel pumps assembly and visually inspected it. Everything seems to be fine.

Went under the car to double-check the fuel filter (without success), I found something interesting instead.

One of the wire in the o2 sensor connector is loose, as you can see in the video. I'm going to fix it tomorrow morning (will replace the connector). It is the passenger side o2 sensor, it probably explains why I got code 64 showing up (and why I had the code only since I replaced the fuel filter. The connector is fixed to the fuel line... I probably broke it while working on the fuel filter).

But I'm still scared about the knocking noise.

Started the car this morning to park it in and out of the garage and I didn't hear the noise, but it is still a concern.
