No injector buzz when cold

I have been noticing in the morning when ambient temp is around 38-40 I have no injector buzz and around 45 I get a weak buzz. The truck starts up just fine and miss or low power. Once it warms up injectors buzz loud. What could couse no buzz when cold?

Sounds like the start of a stiction issue... I'd give Archoil or Rev X a try. Also, what is your FICM volts at KOEO and running?
