What does pulsating engine mean?

Hi all,

About 6 weeks ago, when I took my Honda Odyssey in for it's routine service, I mentioned to the guy that I had started hearing my engine sort of pulsating (fast, slow, fast, slow). He asked if I could see the speedometer arrow pulsating with it and I said a little. Afterwards, he said it wasn't a problem. Now it's getting more severe. What does this mean is happening, and will it be expensive to fix? Does it hurt to drive with it like this? Does it use up more gas, because I've noticed a 3-4 mpg decrease in my fuel mileage. I'm very happy with the service at this Honda place, so I hope I can trust that he knew what he was talking about. Maybe he knew it would get worse without hurting the engine, and we could fix it with my next servicing. Thanks.
