If you ever did find the problem please e-mail at make sure you say something about the Oldsmobile. I am having the same problem ,but it also likes to start half the time, so i think it's something with the spark plugs or the plug that goes into the plate that holds the spark plugs on it. What is interesting is that when you drive it for about 1-2 miles stopping and starting (going) fast it like slowly goes away,but then when you start it back up it is back.
