The front mount looks fine but I can't really tell because of the metal around it. How do I tell if it's bad?

I pulled the tb today and it was really clean inside so I threw it back on and checked the uim bolts and some were kinda loose so i tightened them up and it wasn't hesitating while revving anymore then I got to looking and 2 vacuum lines were split so I wrapped them in electrical tape and it seemed a lot better. I took it for a drive and it pulls harder now but the ltft's are in the 10's ish at wot and the stft is at 0. Also i'm still getting up to 6* of KR at WOT. Gonna seafoam it later and see if it makes a difference.
