The truck will high idle then idle low then die when I try to give it gas. Its also running rough. Am thinking it might be my full injectors or throttle body. I really don't wanna replace these until am sure that's the problem

Spray choke cleaner at the base of the tbi unit as the gasket may be blown. If rpm changes or smooths out it is. Check fuel pressure as well. And scan for codes.
