Kinda off topic, but you can get around the mobile phone search issue by clicking the search button until it's window pops up, and click on "advanced search" to open the search page.

Ayways, I doubt this is knock if the engine is cold, because knock (ping, etc) is actually preignition, where the mixture is ignited prematurely from the compression causing the fuel mixture to hot spot and ignite before the spark hits. This is far far less likely when things are cold, but not impossible.
More realistically, for those mentioning stumbling and hiccups, the theories of condensation or something with the fuel delivery system, oil delivery, or air metering in the intake, all make sense because things are way outside the normal operating temps. Maybe try a full tank from a different station just to rule out winter-mix fuel quality?
I've retired the idea of letting the engine idle to warm up when it's cold. I prefer to start up, idle for 10-15 sec to get the oil flowing, and get moving immediately but drive very easy/low RPM until the temp needle hits the lowest cold mark, then drive normal at low rpm until it's at temp. I've come to understand this gets the oil flowing where it needs to be and warms things up more quickly.
Also I'm hearing two different complaints; engine noise/click/tick, and actual hesitation/hiccup. Please be clear when describing your issues. I have noticed some idle clicking, more so when it's cold, but from all the boxers I've owned, I haven't heard anything unusual thus far. This thread is making me curious and I'll pay closer attention to see if I notice anything abnormal.
