Here's a test to help isolate where it is coming from. Start the car let it warm up. Adjust the idle a little faster than normal between 1500 and 2000. Unplug wire #1 and observe the drop in rpm. Then replace the wire, then move on to the next one. What you should see is that the rpm drop is about the same for all the cylinders. If you unplug one wire and there is no drop or drop is much less than the others than you know there is a problem in that cylinder.
