2006 LS V8 - recently started to have a slight stumble for a few minutes at cold start - goes away once warmed up. No codes via OBDII or dash lights. Its odd but it seems like I can feel it thru the accelerator pedal while driving right after start up - a bit of vibration/feedback. Aside from possibly a failing COP(s) other likely candidates? Not long ago manifold was removed to replace a cooling system hose. Thx
