I will definatley replace the rings on the IP. I dont think its because the rpms drop. This happens randomly it will idle smooth and then rought, like its missing or not getting fuel for a second the smoothes out again. My guess is that it is sucking in air. I will try the seals on the IP and see if that helps. I am also thinking that the leak is getting the connection on the IP wet and causing a bad signal to the ip, because when I clean the connection on the IP it will be fine for a day or two.
