KA24DE running rough...Timing?

[snappy]

The same thing is happening to my car- it shakes and misfires at idle. I got all new spark plugs and wires, but is still does it. I also did a compression test and all cylinders came back at 150. I also put in a remanufactured head with new valves- the works, after I warped my previous head.

Someone told me to take out the spark plug wires one at a time while the car was running to see if there was one cylinder that was causing a problem and when I took out spark plug wire #4 there was no change, while the other cylinders drop in rpms when the wire was removed.

It happened all of the sudden about 2 months ago, do you think it could be the timing? I had it toned about a 2 years ago... Any thoughts would be great.
