I hope you find the problem before Mon. Morning when I take mine in. I am experiencing the same problem and have been for short period of time. I cant take it anymore, I changed my rotor button, cap and plugs. This problem is driving me nuts. I must give in and take her to a tech with proper tools to diagnose her.

"It cannot be emphasized too strongly or too often that this great nation was founded not by religionists, but by Christians; not on religion, but on the Gospel of Jesus Christ. For that reason alone, people of other faiths have been afforded freedom of worship here." Patrick Henry 1776
