Slow almost no go when cold; normal?
Slow or no go until she warms up, is this normal?
I am talking about my 2002 Excursion 7.3. I love my diesel, and this is the only one I've ever owned. I bought it used, and it's always been very warm blooded, meaing that until she warms up, she either wont go or will be very slow going. She always starts and runs fine, but on cool mornings she will resist going and no matter how hard I push the gas pedal, she wont rev up until she's ready to rev up. It's definately different from the gassers I've driven.
I thought it was just a normal thing for these diesels to have to warm up before they loosen up and do what we want them to do.
Today I was told by someone who experienced it with me, that this may ba a transmission problem. Just as fyi tho, he doesn't own or drive a diesel, so Im not sure how much he knows, but he made me want to ask.
As additional background, two summers ago we were towing a trailer through the Big Horn mountains and lost the front seal in the transmission. The Ford dealership fixed it and everything seemed to be fine as far as I knew. She's always been sluggish and cranky when shes cold ever since I got her. Normal ? Right?

That seems a little extreme to me. My '00 is a 6 speed so I don't know about an auto but mine isn't nearly that bad when its cold. It does do better once its warmed up but it will still get up and go when its cold.

Some sluggishness is normal, and I never push a cold engine anyway. Your exhaust back pressure valve may be causing some of your symptoms, but it sounds like more than that. I can tell when the EBPV opens up-it's like releasing the brakes. I had it unhooked for 2 or 3 years but hooked it back up for faster warmups.
