I had the issue also. It started as a small hesitation when I was heavy on the gas. Slowly became so bad I could not get above 55mph without it cutting out. It turned out to be so much oil in the spark plug holes it would ground out the plugs to the heads <img src="/forums/images/graemlins/smile.gif" alt="" />. Mine was driver side, but it could be either. I replaced the spark plug tube seals, it fixed my problem.
Good Luck <img src="/forums/images/graemlins/cheers.gif" alt="" />
