They found a bit of sludge when they pulled the cover and there was some speculation that this might have been the source of the problem. And yes I am deligent about my oil changes. BUT I was told to start changing the oil every 2k. Seems this was not the first one that had sludged up.

Thank you for all your replies. After 4 weeks being in the shop I finally got it back yesterday and the verdict: It was a timing chain that had jumped a tooth on the right side.

First; thank you for your input. I don't know if they have checked for any vacum leaks. The list of things they have done is long. They did check the crank shaft sensor and it was allegedly fine. I agree with the many that have said there must be a common problem that is affecting the cylinder bank. I doubt the fuel injectors were bad but they were replaced anyway. I/2 of the cost of those is all I am on the hook for. Subaru is picking up the rest. They swapped the computer out of ours into another 01 and put the other computer in ours. The other car ran fine and ours continued to miss fire with the other computer. Now for the latest. They are pulling the engine and replacing the right bank cylider head. The thought is the valve guides are cooked. The Subaru tech line has been guiding the diagnoses. They insist that it is something mecanical I have to believe it is electrical. After 5 subarus with 4 cyl engines that all lived past 100k with no problems, I think that the 6 is cursed. Give me my BMW 6 any day. Thanks again.

Fuel injectors were the first thing done. It passed the leak down test. Compression was within specs. I used the term "burned" for the valves and that was incorrect. They think they are carboned. Also it has a timing chain. I was told if it was even one tooth off it would not start. Coil packs were checked and are reportedly ok. It is one bank that is running poorly. And it just went. No early miss firing or anything that would make you think it was about to die. Thanks for your reply.

My 01 Outback H6 wagon has been at the dealer for 3 weeks with a frustrating engine problem. It has 46k miles. Purchased new The check engine light came on. At idle the engine was misfiring on 1,3,5, fuel injectors were replaced on those cylinders. Problem continues. Computer was pulled and sent to Subaru reinstalled and problem continues. Plugs were checked, leak down test preformed, data stream completed, problem continues. Now they think the valves are carboned. The dealer (who has been great!) is as frustrated as we are. I can't believe that a car that has this few a miles could burn valves. They have relaced all the fuel filters air filters and checked all the electrical connections. Still will not run smoothly. Anybody?
