White smoke on startup
I have a completely stock (never had a programmer or anyting on it) 2007, 2500,with the 5.9 CTD, 20000mi, synthetic oil, clean air filter.
Problem I'm expierenceing is when I start the truck after it's been sitting all night it will put out a good amount of white smoke. I can watch it come out the exhaust pipe and the smoke appears to studder or pulse out of the tailpipe as if it was one cylinder only pushing the smoke out. It's quite a bit of smoke, nice sized cloud and it smells sharp like the engine has a bad fuel/air mix.
If the truck has been sitting for a few hours to "cool" down it will smoke again but not as much.
The engine feels like it's "missing" when the smoke is coming out but once it runs for 30 seconds or so it smooths out and smoke stops.
I don't appear to have any performace problems and average 16.7-17.3 mpg in the city (according to the overhead).
Havn't changed the fuel filter since I got it but I'm going to go and pick up the stuff I need to do it tomorrow.
Any other suggestions??
