Injector Knock to Engine Loping/Miss

Hello,
I recently changes out my injectors due to them knocking loudly, but the engine was smooth.

I changed them out with rebuilt ones and now the engine has a lope or miss. The engine shakes and it has an audible miss from the exhaust. It is very quite running know but has the lope.

I changed out both fuel filters and this made no change. I did notice that my old injectors all had the same # in the 400 range and the rebuilt all have this 135 # on them. Does this # mean anything or can I have bad rebuild's???

Any help appreciated!!!
