I'm having the same problem, and I've been trying to figure out what it is. On my truck, it belches blueish/grayish smoke at around 2300 RPMs (depending on temperature) in neutral, 1st and 2nd gear. 3rd - 5th it doesn't do it. If my temperature gauge goes to around the "A" in normal (that's where my temp runs for some reason), the problem goes away.
I have noticed loose exhaust bolts at the driver's side manifold collector, and upon tightening them, the problem either went away, or decreased dramatically.
The truck is also can't even move out of it's own way until the temp reaches the "O" in normal. Can somebody please explain why the truck does this? It's about to drive me
I'm guessing there is a fuel deliver problem during these conditions, but I don't know what to do. Not getting any codes.
