Rough Idle And Blue Smoke On Startup
 

usually when the truck is cold, weather the wait light comes on or not, the truck turnes over a couple more times than normal and when it does start it idle's rough for a few seconds and puffs out blue smoke. What could this be? The dealer had it for 2 days and ofcourse found nothing. :madd:They probable got the diesel guy who rode in it with me last that hated the turbo whine(what a louser, he even had a cummins)! Could this be an injector problem? What about fuel filter?

Mine does this when the fuel filter is ready to be changed. Roughly around 8-9k miles. Always clears up after a fresh filter.

I asked the stupid dealer people about this and they said it was too early. Only every 20,000. I just walked out. I will get it changed soon.

Here's more then likely your problem!

Thanks Buckshot. :U:

No problem. I had the same problem with mine until the flash was done.

Mine did the same thing for a few months...turned out to be an injector ready to die (which did die last week).

It could also be a bare wire on the AC compressor switch (near the compressor), but IIRC, they fixed that on the 05s.

steved

ya'll are making me skiddish about the 3000 mile road trip I got coming up

I have had the reflash done twice and still have the same problem at times.
It doesn't matter if the fuel filte is new or old..

Perhaps your grid heater is not working right then.

I am having this same problem right now. Anyone know what it might be? Rough idle on morning start and blue smoke?
