Cold engine knockin'

The engine gives an audible knock until it is warmed up. Now, I'm no expert so allow me to ask a basic question. What causes engine knock? Overly rich or lean mixture? It must be the cold mixture because it goes away once engine is warm.
I've replaced the coolant temp sensors so my next step is the AMM, right?
Last week the check engine light came on twice and stayed on about 10 minutes each time. Have not seen it since however.
All thoughts appreciated.
Todd '90 900 & '94T-conv.
