My car lately has been hesitating in neutral. Check engine light didnt even come on. I used my peake code reader today and it gave these results...

16, E9, FE

Table 16
E9 ''Catalyst efficiency below threshold, CYl#1-3''
FE EVAP large leak detected

I read the codes but couldnt understand them. Can someone please explain to me what's the problem and what parts I may need? please help!
