05 6.0L Diesel doesn't like the cold
I have an 05 F350 with 85K miles, and 10K miles on egr delete, new head gaskets and studs, new oil cooler and CAT delete. This is the first time I've had this truck in weather below 30F consistantly.
For the first two months it was totally normal: a little smoke on startup, high idle kicked in and in a few minutes it was running great. It has, however, become more difficult to start with more smoke for longer periods of time. The high idle is not kicking in (still below 30F in the mornings), and it lopes a little bit when it first fires (maybe 5 or 6 seconds).
These problems go away when it is running at operating temp (except the high idle, of course). I have a short commute to work, only about 2 miles: could this be part of the problem? I take it out and run it for about an hour once a week to get it good and warm "blow out the carbon" so to speak. Any help/insight would be greatly appreciated!
Also, I'm looking for a cheap diagnostic tool (I've returned to school and am feeling the financial sting), any suggestions? Thanks!
