I've read through no less than 10 threads about cyl deletion and also googled a mess of websites. I haven't quite gotten an answer I'm looking for yet, so here goes with my question:

IF you block off the air going into and out of a cyl, (thus trapping it and it would be compressed then decompressed as the piston moves) while disconnecting the fuel injector and spark plug, what happens? I understand that the engine runs "rougher", but I haven't found a reason why this would be bad.

It's late and I'm tired, and maybe I've read so much that I've confused myself.
Can anyone explain the effects of doing this in a simple, easy to understand, way?
