Uh oh. Now I'm worried about whether you have a combustion or valve issue. Grey/blue ish smoke is usually oil. If your rings are worn, they may be seating better at higher rpm and pressures and not holding enough compression when idle. It would be starting okay, because the cylinders haven't expanded from heat yet.
Fingers crossed. Have the compression checked. Its fast and simple.
