how can i find out for sure what the problem is before i just go buying parts i know the fuel pump is good also ran injector cleaner through the fuel and it didnt work so im thinking its either the fuel filter or injectors r bad i dont think its the tps sensor bc its only at start up. it starts fine but when i hit the throttle it takes a few secs to rev up and almost wants to die but if i rev it for a little bit it goes away

Disconnect your temp sensor see if then start it and see what happens, that's my fix for everything.
