Is your 7.3 cold blooded ..?

[stufarmer]

Today's another beautiful 94* day here in Florida. My 7.3 Tremor has about 1700 miles on it. When I first start driving for the day, it acts like "the choke is sticking". It surging while I try to maintain 25 mph, until I can get out of the neighborhood. It's not as severe if I drive faster, and gets better in a couple of miles. It's done this since new, no CEL, just wondering if its the nature of the beast.

Mine does the same and I heard many others say so as well. Not sure if all of the 7.3's do it but seems to be common enough.

Mine does this as well. More pronounced with light throttle

 

[Jrod250]

Same here

Mine does it when its in open loop(still warming up). Its tune related and can be fixed if you ever flash the truck. The low 1st gear and tight converter amplify it drastically.

It's not just the 7.3 as I've had many trucks act like a woman on the rag til they reach temp.......it's normal.

My work truck with the 6.2l does this. For whatever reason, it does not like light throttle applications, when it's cold. Mine only last the first couple of minutes of driving or if I let it idle for a few minutes before driving it does not do it. I call it a Fordism (An unexplained phenomenon that does not cause any problems).

My Raptor does this....

Definitely similar issues with my 7.3. When cold, she surges and is uncomfortable at low speeds. When hot, she surges and is uncomfortable in stop and go traffic.

The low speed fuel mapping and the torque converter are wonky on the 7.3, in my experience. If I had to list what I'm underwhelmed with on my truck that would be 1a and 1b.

Yes mine acts the same way since new, just exactly the way you described it.

My tremor does it and my sho does it too.

Here's a slightly newer thread with related information that applies to your question.

Truck lurches when parking brake is applied

This is my first superduty ('21 73 Tremor), so perhaps this is normal and I'm just showing my ignorance. On my '18 F150, when I was hooking up to my trailer I could position the ball under the coupler, apply parking brake, and it would not move at all - stay exactly where it was when I put the...

Same. Seems to settle once coolant reaches 65C (149°F). I usually remote start before leaving if I can and let warm up. The idle smooths noticeably at that temperature.

This is where I'll need to be as my commute is 2 miles each way.
