misfire p3000 after catalytic converter replace

I just replaced a clogged catalytic converter drivers side on my 2003 H2. Now I,m getting a misfire code.
Truck runs good once underway , but at idle it runs rough, rpms drop and coolant temps start to rise.
I,m thinking it is vacuum related. Anyone else have this problem after replacing a cat ?
