Just going to describe a few symptoms and what the trouble turned out to be in case anyone is experiencing this right now. Easy fix for this scenario!

Model: 2001 Outback Ltd (4 cyl, Auto)

Symptoms: Poor acceleration, and intermittent engine shudder, followed by flashing Check Engine light.

Background: Prior to the last oil change, I had noticed some sluggishness while getting up to highway speeds, nothing too major, but unexpected, and with all the new roundabouts in town, it got my attention because one needs to be able to accelerate quickly at rush hour. So, a few weeks ago, I got under the car to change the oil and do a drain & fill on the tranny (and gasket change) and having extra time under the car, I of course look around at everything, and noticed the #2 spark plug wire boot was sticking out further than the one next to it, so I reached up and pushed it back in until I had a (slightly) satisfying click, and pushed on it again from up top of the engine bay but it's hard to get a good shove on it because of the window washer reservoir in the way. Anyhow, I drove it like that for several days, only to notice the performance continuing to degrade to the point that every time I hit a big enough bump, I'd have to stop the car, and push on the plug wire boot.

Troubleshooting: Removed washer reservoir, pulled plug wire boot completely out. Last three inches of what is supposed to be nice pliable rubber was kind of dense hard sponge-like, leaving dark marks on my fingers. So the wire boot had been experience a tremendous amount of deteriorating heat. I examined the conductor connection inside and found it looking quite normal, but wondered why it was not staying on the plug.

Resolution/Conclusion: Turns out the spark plug itself had a missing tip that threads down onto a stem. I never saw this when I installed the plugs, and have absolutely no idea how or when the tip went missing, but clearly explains why the plug wire had nothing to snap onto. I bought a new Bosch Platinum plug and re-used the existing wire for now, because I don't know where to source just one wire, other than a junk yard. Car runs like it is supposed to, and I no longer fear darting into a round-about, especially with the kids in the car.

So I just bought a 2011 and it’s doing that shudder thing after stopping but only in automatic mode not manual! I don’t work on cars myself so I have no idea what to look for and or know how to fix whatever it might be. Can you recommend anyone who works on cars that could help me out fixing this problem!? I just paid $8,000 for a 2011 outback and I can afford to lose it all! Uugghh, this is so irritating I am mad at myself for not listening to the reviews before I bought the car. It didn’t do it when I test drive the car for like 30 mins but then later that day after going home and leaving again it was like clockwork!!!?

Where are you?

There are plenty of members on this forum that can help you find a reputable shop that won't rake you over.

This gen car will go 100s of thousands of miles with regular maintenance. Friend of mine has one that is about to flip 200k miles with its original engine and cvt. It has had the valve body replaced.

Regular maintenance is all the fluids, not just engine oil, the timing belt and components, keeping a good battery and making sure the grounds are corrosion free and cleaned regularly. Most maintenance can be performed in your drive or garage.
