WHY DOES MY IDLE NOT CHANGE EVEN IF I REMOVE OR SWAP 2 LEADS OVER

1998 Holden Commodore • 140,000 miles

My VS is idling really rough. I have changed the leads coil packs and spark plugs. I am getting spark but when I unplug 2 leads there is absolutely no change in the idle the spark plugs have been changes 3 times as has the coil pack and leads. Its like no matter what I do my car will only run on 4 cylinders Help Please

The 2 cylnders that you unplugged are not working. Have the compression checked to see if they are within range.
