Rough running when cold. Please Help.
I have a late 99 PSD. When I start it after being allowed to cool off it runs kind of rough and smokes a lot. That's even if it has had the block heater plugged in.
Allowing it to warm up is almost embarassing as it smokes quite a bit. After say,10 minutes of warming up I will drive away and the truck feels like it it missing and as near as I can guess it feels as though it's only hitting on six cylinders.
I now take it down the street and put my foot into it. Then it will start to clear up and the smoke gets to be less and less. The truck runs fine once it's heated up.
Has anyone got any idea what might be causing this? I should also mention the smoke is kind of blue in color and basically smells like raw fuel or maybe half burnt kind of like the old caterpillar "c" series loaders when first started in the cold weather. Block heater is working. Please tell me it's nothing too serious because I really don't think I want to spend a whole lotta dough on a truck this age!
Just to clarify things the truck has about 180,000 miles on her. Thanks!
