I somewhat of the same problem, changed plugs it was a little better. After I ran it for a minute or two, I took plugs out and one was wet. Put them in started the car and pulled the plug wires off one at a time. When I got to #4 and #7 plugs there was no change in the idle and you did not hear the spark jump either. I am in process of changing them out. Good luck.
