Like the title says if i let my truck sit there and idle for o 30 seconds or longer when i take off it pumps out the white smoke. It seems to be running fine and had injectors tested bout two months ago and they were fine but problem just started. Any ideas thanks

having the same problem, blows white smoke terrible at idle..seems to run fine but heard thats commonly injector problems, curious to see the posts on this thread

Injectors need say anymore? whats happening is the injectors have eroded at the valve seat and now never shut off completely the fuel, and fuel is "drizzling" on the exhaust stroke and never burning, it can lead to engine failure if allowed to continue hope more is wrong or hard to get replaced on just that Monitor for fuel in oil OFTEN, reading others we have come to the conclusion that water in the fuel allowed to pass the filter by use of fuel additives that emulsify

I'm in the same boat as you friend, doesnt crazy white smoke at idle but when you take off from sitting for a bit idling ill get a good bit of white smoke until im midway through second, sometimes though not always? so im very anxious to see what is said had my injectors tested in the same time period as you
