Truck has problems starting in mornings once it starts I have to let it warm up at least 15 minutes once it's warmed up it runs good. If I don't let it warm up it sputters and bucks and I live in florida

Scan for codes and check fuel pressure with a gauge https://www.2carpros.com/topics/engine/throttle/throttle-body/maintenance/clean

I fyou don't do the basic things I sent to you then you don't know where to go. You have to scan for codes and check fuel pressure in order to properly diagnose what is exactly causing your problem. Also check for a vacuum leak and fuel pressure should be 60-66 psi
