I have a 02, F-450, for awhile it had smoked blue, white smoke until it warmed up, I mean as soon as the temp gauge moved it would quit smoking and run fine. However the last two days it doesn't want to come out of its funk.. It starts fine an idles good, but no high idle, that hasn't worked in some time.. It fights to get over 2000 rpm has no power and is sucking down fuel. It went from 13 to 5 mpg. It's my service truck and weighs 12,800. Any ideas? Seems to be getting plenty of fuel, it just reakz of diesel out the exhaust when idling cold. I don't hear my turbo spool up either. I'm thinking my exhaust back pressure slave is stuck, not sure though. Would appreciate some help!

Thanks for the reply, gives me a good place to start.. I bought this truck at an auction about 18 months ago, cheap, because it was cold and smoking. I've never really understood what was causing these cold run issues, but like I said as soon as the temp Guage would move it would quit smoking and run Prefect. And summer days where the low stays at 60 degrees, no trouble at all.. Thanks again..

Possible FICM trouble?

Have you tried plugging into a tuner and check if the truck is throwing any codes?

No I haven't, I don't have a scanner, this is my third powerstroke and I've never had any issues where I needed one. I drove the other ones to 250,000 miles each all stock, I've never had any trouble till this one, I operate heavy equipment and generally being around diesels as long as I have been I can diagnose what's going on, but this has something to do with cold weather, nothing mechanical would just go away everytime the truck warms up. I should find a scanner I guess, it very well might tell me what's up!

Check the fuel filter for signs of oil, which would indicate an injector o-ring.

Turned out my main problem was a plugged cat, blew the donut gaskets to the turbo adapter, found my plenum leaking oil, changed glow plugs, oil change, fuel filter replaced, new air filter, cut out the cat and it's running good again. Smoked some blue only when cold, but it's always done that.

I still have the original blue smoke when cold, as soon as the heat Guage moved it clears up. I mistakenly thought that my other troubles were from the same source, but having a plugged cat is what caused the power lose and poor fuel mileage. I fixed the gaskets on the turbo adapter and it ran worse, seriously had a WTF moment! I bypassed the intercooler to make sure I didn't leave a tag in it. Then I started looking at exhaust.

I am glad I don't have a kitty.
