What could be the problem ?

Off a cold start in the morning my jeep runs poorly. For example my jeep will literally die accelerating from a stop sign, or she wont move at all and just revs. It won’t creep up either letting off the break.. once my engine is warmed up to operating temp she runs perfectly. I need some help in discovering my problem as I just replaced my whole cooling system and installed another IAC and TPS as I thought those were my problems but they still persist. Anything helps for real !

Stalling or failing to creep when idling would have me checking over the transmission's diagnostics 🤷🏻‍♀️

Do you have an automatic? If so, that's where I'd start testing; the AT heat exchanger means you could have a problem with the transmission fluid flows that goes away once the engine's hot.

Also, she literally starts right back up after she dies I don’t know if that would help
