Check light comes on. Test kit says misfire cylinder number 6. So I changed plug and wire on that cylinder still running ruff.

Check the compression and injector on it

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
