From what I've read the seals will go on all cars after 20-40 thousand kilometers. You're better off to do it either way and I guarantee you will notice it! I did mine 2 months ago and it was very noticeable.

I don't know what's causing it to be intermittent but if it's not smooth you may want to get a new set of NGK spark plugs. I was using Bosch and they were misfiring so as soon as I put in the NGKs it went away.

From what I've read online bad Cam Position sensors can cause performance losses but I don't know how to diagnose that so you should look it up on e46fanatics.
