Other than the timing....faulty sensors can cause a car to act up too....IAC, TPS, etc. And more obvious things like a weak ignition. So you can't tell what the marks are on the balancer? I had a hard time reading mine on the factory balancer too...cleaned it up and I was just barely able to read what was etched in there.....a new balancer will fix that right up, but talk about a pain in the ***....lol...
