I did drive another and it was just like mine. How many should I drive? Perhaps just these two do it. But these are the only two Subarus I've ever driven. The dealer has told me that there's nothing wrong with it. Says it's just the super sensitive electronic throttle and takes getting used to. Now that it's cooler and I don't need the AC, it's tolerable. But it's my first and last Subaru.

The 2.5 engine used in the Impreza and the larger cars, like the Legacy and Forester, is the same, right? But, the oil filters are different. The same thread/pitch and gasket size, but the Impreza gets a teeny tiny cased one and the other cars with the same engine get the bigger cased one. Why? Why wouldn't Subaru just use the same filter on all the 2.5 liter engines. The last oil filter I bought was the only one the dealer had, the larger one, but it fits the Impreza fine so I'm using it. Problems? Just seems odd to me.

My 2006 Impreza does it at all speeds. Worse with the AC on. I was told it's just part of driving a Subaru and that you have to get used to it.

Actually, the car runs smooth as silk when using the cruise control, or accelerating, or decelerating. But if you try to keep it at any constant speed you get the buck, surge, brake, lag, buck, surge, lag, brake, feeling. I suspect it has to do with the drive by wire electronic throttle since you can stop all the bucking and jerking just by taking your foot completely off and away from the gas pedal. Would still like to reset the ECU just to see if that makes any difference. How would one go about doing that?

My new 2006 Outback Sport with MT feels like this all the time and I really hate it. It just annoys the heck out of me. How do you reset the ECU? I'd try anything to get rid of the bucking and surging and braking. Thanks.

New 2006 Outback Sport Impreza, 2.5 liter engine, 5 speed manual trans. Nice care but has an odd characteristic that is driving me crazy. Car is fine when accelerating or decelerating. But any time you are just attempting to hold a certain speed, backing off on the gas pedal and just keeping the speed the same, you get a sensation that someone is tapping on the brakes, or that the car is slowing and then speeding up. It feels like a constant bucking back and forth. Not violently, but subtle yet definite. Others have driven the car and they can feel it too. So can passengers. When the AC unit is on, it's much worse. I did take it back to the dealer and they said nothing was wrong with the car. Their "technician" said it was just a super sensitive electronic throttle and that you have to take your foot completely off the gas pedel unless you are actually accelerating. Said I would get used to it. I haven't. Any ideas? One last thing that may or may not be related - when you first start this car up in the morning, everything is fine until you put it in gear and let the clutch out the first time - you have better be ready to push the clutch back in quickly, because the engine is going to self rev to about 3500 RPM. It does this for about 10 seconds, then settles down and is fine for the rest of the day. But every morning, first time you put it in gear and let the clutch out, it revs to 3500 RPM all on its own. If you don't get the clutch back in you'll take off like a bat out of .......... Any ideas on that? Thanks to all. Nice car but these two things are very annoying.
