Sounds like starving for fuel. When did you last change the fuel filter.

Air intrusion. Always shows itself when Temps drop.

When it bucks it sucks, air that is.

Is your hi idle solenoid working? Did ya cycle the foot pedal one time?

Get some clear hose and trace where air is getting in . Do you have stock Water separator on ?

 

[83ford]

No water seperator at all and gonna change the filter tommorrow and I think it's one of the caps it was wet today so we shall see after school tommorrow

Def sounds like air intrusion. Also I would check the HIS like OLDBULL8 said.

The hi idle does not work but I mean you would think sitin there with the throttle down it wouldn't matter

What do your injector return lines look like?

Also, I can't remember who, but a member did a video of a setup where they checked for air in the fuel lines. I'll try to find it.

It was a cap i replaced it and the orings and so far so good but know im noticing a huge puddle of either fuel or oil under my truck at school I gotta check out tommrrow.if I was fuel Id think it wouldn't start so easy as it does so im thinking im leaking oil bad

Glad you appear to have fixed one problem but I feel you created another. Generally talking when you disturb the return line system to fix one leaker you create another leaker. so its best advise to change out the caps, hoses and o rings on all injectors.
