No check engine light? Do you know what cylinders are misfiring? Have you checked for goos spark on each cylinder?

yes check ingine light is on, cylinder 3 missing, goos spark?


Then you probably have a bad injector which would cause a problem. You can check resistance and compare to the others if much difference replace otherwise swap with another cylinder to see if problem moves with injector if so replace. If not you will need to do a cylidner leakdown test to check for a leaking ring or valve.
