99 E350 PSD, 113k.
Occasionally when its very cold (below freezing) my PSD likes to do something funny. Startup is normal - GPR kicks on, crank, fire. Idles great. I let it idle as long as I can which is up to 10 minutes if I have the time, or 2-3 minutes if I'm late for work
The road I take is uphill about a half mile to a stop sign. As I pull out, everything is fine. I keep very light throttle since its cold. A few times now, about halfway up the hill, it starts "missing" and I mean its just like dropping a spark on a gas vehicle. I lose a cylinder and it chugs a cloud of unburnt fuel (bluish white). Normally that's all I get from it and it behaves after the stop sign.
This morning, it didn't want to move from the stop sign. It was idling rough (missing a cylinder), and when I hit the accelerator it didn't respond. It was as if the computer was only letting me get about 3% throttle. I put it in neutral and let it rev a bit and I got the cylinder back, put it in D, and it never gave me another bit of trouble - not on the way to work, not on the way to lunch, not on the way home.
Scanner reveals no codes pending, no codes set.
I considered the following:
- bad fuel; although it has done it over a few weeks and a few different fuel supplies.
- fuel filter; although it was changed about 8000 miles ago, it could be a problem.
- fuel gelling; but wouldn't that cause more issues than just one time in the morning when its cold?
- water in the fuel; but I opened the drain on the filter housing and only got diesel. I also verified that the "water in fuel" light is operational, but that may not mean anything.
Do these symptoms point to anything specific to you folks?
