i have a 99 7.3L and if it doesn't reach 140ish motor tempt when it's about 30 degrees out it'll stall out or it'll stall here and there before it's a steady idle. It gelled up last December -ish and we managed to get it running and change the fuel filter but now it's stalling again. Any suggestions on what could be the issue?

 

I'd post in the 7.3 section. Lots of gurus to help there.

 

Welp, nevermind. I see that you have and you're getting some suggestions there
