The professionals will no doubt offer good advice here. My own experience was with a 99 where the head gaskets were failing; I found an economical shop in northern Vermont that swapped out a 2.2 for the 2.5 Outback; less power but I got some years out of it. I paid around $1200 or so all in.

A friend cleared the codes and then other codes did not come back, but the battery was low he said so not sure. Towed the car to a shop who said he would let me know tomorrow. I spoke to the previous owner who called me out of the blue today. The shop where it was towed said it may be the timing belt jumped.

We checked out the forward O2 sensor and when getting the breather apparatus off saw that the plug was disconnected anyway with a zip tie holding up the O2 from the cat converter end. I decided to have AAA tow it to a mechanic so will let them figure it out.

I may have left out the letters assuming that they were PO; PO452; PO73; P1443;PO0031 My friend assumed that it was the transmission fluid being low so we got a couple quarts but that didn't make any difference. It may be a tow through AAA now to a mechanic who is better at diagnostics.

codes that came up, were PO452; 073; 1443; 0420 and 0031. The cat code I knew about, not sure what is going on with the others.

Thanks for the advice; a friend over an hour away said he'd try to help me on this, as this is a white collar town hardly any do it yourself mechanics, and people have been avoiding one another during the pandemic.

It was throwing the code on the downstream sensor; don't have device to check it at this point. What would be the symptoms of the upstream O2 sensor messing it up or the cat converter being clogged?

Most of the electrical replacement parts were OE; previous owner replaced the cat. converter; one friend's high level mechanic said it could be cat. converter being clogged. Coil breakdown happened a few months ago and was replaced by mechanic.

I drive it every day; recently replaced lower O2 sensor, wires, plugs, coil. Upper O2 sensor I thought was ok as previous owner replaced Cat converter in last couple years.

This happened to me earlier; it went from relatively minor loss of power earlier to now no power to go up hills; 2002 Forester will idle, but very little power. I checked previous mentions of something similar and one owner said that changing the O2 sensor in front helped him. I tried to jack the car up earlier roadside and found the forward O2 sensor but did not see how to de couple it if that would help. Also thought low gas might be an issue so added a gallon, no change.

Tool rental availability has been better at Auto Zone and they did not offer the pressure tester, and in the past some of their tools are not available. I just checked with the local Advance Auto, so my bad, they have a multi part tool rental that is $265 that goes back on the card when you bring it back. I assumed they would not have it because they have been a no go on brake tools, breaker bars, etc. in the past when Auto Zone is a green light.

I remember they were so expensive that you would go to the junkyard to get them or have a radiator service place boil them out to get them to function better.

I checked with both Auto Zone and Advance and neither had one to rent; just to buy, and I would only use it once if I bought one.

I lived with a leaking radiator for several months, thinking it could be a hose or something else. I finally got around to replacing it which solved the problem. It's hard to believe it was the original radiator as that is a long time for them to last. The lower clamps were all frozen and had to be cut off; the transmission cooling lines and lower large rubber hose clamps. The leak was on the side where the cap screws in. The problem of diagnosing it was that I could not find a mechanic with a pressure tester. I got confirmation from a friend after running car for a while.

If you want it perfect, you're going to have to replace all the "substandard" parts which will keep you busy for a long, long time. Ball joints, make sure they are all OE and in good shape for the duration; all tie rod ends etc.. Not worth my trouble and if I had known that the nut could have been turned with a torch, would have done it myself and saved all the pain and aggravation.

Rock Auto has a very efficient search algorithm. Only Moog, Mevotech and AC Delco for part providers. https://www.rockauto.com/en/catalog/subaru,2002,forester,2.5l+h4,1378739,steering,tie+rod+end,7428 You are going to have a few lemons with every car parts provider. If you get them from Subaru, you will probably pay 2-3 times as much.

Before and after on alignment: Last time: https://i.imgur.com/UH27Cgk.jpg Today, different shop: https://i.imgur.com/WJkLK8y.jpg

I'll ask them why they don't use torches; Town Fair tire, generally good. Is the Moog not a good brand for the front end parts?

Nut would not turn, so the alignment facility tagged it as needing replacement; other threads on unit were probably further damaged when mechanic put it in vice to separate inner from outer which he had trouble doing. He put in the Moog unit I got. Mechanic did not know how to approximate alignment, vehicle was not really drivable when I left the shop and had to come back.

The tire alignment facility could not get the bolt to turn to accurately adjust alignment. The nice black mechanic was able to do the bare basics; but the front alignment was so far off when he was done that the car was really not drivable. I went back and when a bay opened up after an hour or two wait he was able to get it closer so the car could be driven. I'm looking forward to getting the alignment done tomorrow. I paid $150 for the job.

I went to the mechanic who had the tools today; a lift in a heated facility, a vice, cut off tool etc. which I don't have. A picture of the separated inner tie rod end:

I have the part; will check with Frank at the shop, who is the manager to see how much he'd charge for the job. I had the alignment done, free re alignment within 60 days; they flagged that part.

https://www.youtube.com/watch?v=1NteheE_cO4 This is a fairly lucid video on changing the inner tied rod end, but there were a number of aspects of the job that scare me that make the job beyond my tool and aptitude level. What is the book time on doing this job for professionals? I went to a mechanic today after getting the tie rod end tool at Auto Zone who has done some excellent work for me in the past but he is too busy, doesn't charge enough. I'll try to check in with another mechanic on the job.

Our family had Toyotas back in the 1970s that were constantly breaking down. Later we got a Datsun 710 I think it was, with the six cylinder engine, just a phenomenal car and engine.

You can't emissions around here without having that working. Unexpected plug failure, how often do these fail? How do they fail? A pollution device apparently. They changed those plugs in 2003, larger, probably as an upgrade.
