just wondering

help me out here please.
when its cold out, say below -10c and i start the truck up i have alomost no throttle input once in gear for a brief while. im hopping that this is a protection feature built in the truck and not a sign of a problem. after a few seconds, say 15 or so, the truck has fine input and once i get going there are no other problems. my last psd a 96 didnt do this, or i dont remember it.
cheers.

Got to give it a few minutes to get up some heat. Diesel don't burn well if it's too cold. Plug it up if you need to leave right away. Let it warm up for a few minutes and cycle the glow plugs a couple of times will also help. 5w40 syn oil will also help.

Mine as do that a time or two.

I just let it warm up a little longer and all was good.

I was in a hurry to leave work to go hunting.

At that temp, the tranny fluid is cold and thick. You need to take it easy for a few minutes until things warm up.

The Exhaust Back-Pressure Valve (EBPV) is also closed under these conditions, making it hard for the engine to effectively "breathe-out", too.

Just doin' it's job....

Yes it makes sence.

When i first start my truck that has not been plugged in and it is very cold outside, say 0 to 10 degrees, I don't have no pedal until she warms up.
