: Smoke and Fuel smell at idle

2004 cc, 149,000 miles, stock.
At an idle, when warm, there is light gray smoke from the exhast, and a very strong smell of fuel. This has been going on for the last 2 weeks. Took it to the dealer monday, service writer was able to see the smoke and almost fell down when the fuel smell made it to his nose. He called me tuesday and tells me that the tech has had the truck running almost all day, no smoke, no odor :confused: . I think, as I told the service writer and the tech, INJECTORS !! Since there has been no fuel in the crankcase yet, no codes, They are still running tests today. Service writer agrees with me. Anybody else think the same?
