Ooops, forgot to reply to your question about gas. I am using 93 high octane all the way, usually Mobil or Exxon.

Thanks Greg (and Texas), Come to think of it, this problem does seem to occur at lower revs. It is very slight, almost makes you think it is a bump (or bumps) in the road, but it isn't. I am due to see the mechanics for installation of an air filter, so I will ask them to do a diagnostic and I will let you know what they discover. It's good to hear that this is apparently not an isolated incident. The mechanics will thus probably know what is going on. Thanks again. Anyone else have this experience?

Hi! I'm new to the forum, but I think I get the hang of it. I recently purchased a 2005 2.5XT outback, replacing my 1997 Outback that blew a head gasket (I think). Rather than repair the old girl, I decided to donate her to charity and ended up buying a new Outback. I am not disappointed. The 2005 Outback turbo is definitely NOT a 1997 Outback! It leaps down the road. It is a nearly totally redesigned automobile. BUT one bothersome item that I notice with my new Outback is that it tends to hesitate slightly (almost a flutter of sorts) as I steadily accelerate the car. It seems like the car might be misfiring or the turbo boost is sputtering a little. This is very subtle, but noticeable. It is definitely NOT turbo lag. I know all about that. Has anyone else experienced this type of apparent misfire or hesitation in a new turbo? Maybe I just need an engine diagnostic and a look at the spark plugs, eh? Any comments would be appreciated.
