You need to have the ICV checked and your compression also. You may have dropped a screw in the intake and bent a valve. When you replaced the plug you fixed the ignition part but I am suspecting compression issues.

doesnt sound like there is a bent valve. only misses when throttle is slightly pressed only a few rpms above idle and en engine light doesnt come on every time. were is the icv located. possible loose screw?

I have never heard a bent valve. Get an actual compression number and let us know what it is.
