Did you check for spark?

I would swap the two and see if it changes the miss fire to the other side then I think we could maybe say that coil is bad.

okay. I will try that tomorrow or friday thanks. I will let you now what happens
 
Could be a bad coil or possibly the Y harness that goes to the coils which have diodes in them so the engine can be shut down from a single wire at the key switch. The diodes prevent the coils from back-feeding each other which would prevent the engine from being shut down electrically.
What engine do you have?

i swapped coils. now the other side does it, but doesn't always do it. i notice the coil that is bad the spark is weak and win you give it gas stays weak. i am pretty sure it is the coil but could it be the Y harness that goes to the coils which have diodes someone mentioned that earlier

If it was the y harness then the miss fire would have stayed on the same side.
I would replace that coil

Well, if you say you swapped and the other side does it sometimes now, then you have it narrowed to that. The coils need a good clean ground.

You did not swap the harness, did you? So go with what you have found.

You need to check for voltage on your kill circuit, that will damage and kill coils...
