Real Cold
HI from I think the coldest place on the planet! just kiddin, I have a 96 PSD today it is -33 here in thunder bay CANADA last night it was -43 with the wind, had my truck plugged in last night this morning when I started it ran real ruff and the check engine light came on it went off when I bumped the Rpm,s up on my module. This Is my second winter with this truck could any one tell me why thi light came on? thanks

Probably an OBD 2 (on board diagnostics) emissions indication due to the rough startup at the very cold temp. The computer put a lot of fuel into the engine to get it running and the oxygen sensor sensed the less than optimum mix of fuel and air. This gave you the light. Increase the rpms and the oil press increased too to give you a better shot of fuel into the motor. The light went out so you are good. With temps that cold I would try to get an oil pan heater too, so the oil and the coolant are heated up. They are a heating pad type element that you simply stick onto the oil pan. It should make the truck a much easier startup. You are using Synthetic oil, right? If not then you definitely should at those temps. because the injectors are oil pressure fired.

I would just do an online search for them. I was looking for a heater for my other diesel, a 2001 Jetta TDI (50+mpg is killer!) and that was all I saw offered for it, the stick to the oil pan type. So I am sure they are available.

Get yourself some 5 or 0W40 synth. I run Esso 0W40 synthetic in my truck, and I was in T-Bay this morning... Started without a hitch. I might want to have the codes pulled and see why the cel was tripped however.

I'll say it again, 5W40, or 0W40 full synth, and no additives. My truck started fine after sitting for 4 hours in that -43 wind without being plugged in last night... It was so cold that it wouldn't hold O/T with the idle at 1500 rpm with the EBPV closed

I'll third the drop the Lucas comment. I'm sure you have all seen their demonstartion gear set in the local auto parts store. I was able to get the Lucas to foam using their little hand crank. If it foams by hand, then it will certianly foam in your engine. Foam=real bad.
I would recommend getting a heater for your oil pan so you are starting the engine with warm coolant and oil. I'm sure it would make a huge difference at those temps. Also, make sure you use a thinner oil as suggested in your owner's manual.

One thing to keep in mind is that wind chill does not affect machinery like it does us humans. Wind chill will cool a motor down quicker but the temperature of the machinery will not go below the true ambient temperature.

I'd definitely go with synthetic. I just switched over to Rotella 5W40 syn, and my truck started up without so much as a rough idle this morning, and it was 13 degrees. Granted, that's not -43 though.
