LegacyGT_in_VT

LOL about Route 7, I drive on that road daily! I will definitely go for a little drive when I get a chance -- check things out at highway speeds, but I'm pretty excited to say the least. Another thing I had a question about was the banjo bolt filter. I have a 2005 so do I want to remove the filters? Or? You also recommended Motul gear oil for the 5 speed?

So, I'm in complete shock. I swapped the Bosch copper plugs with the new NGK Laser Iridiums and changed the positions of the coil packs, and currently have 0 codes. The car runs MUCH better, with no noticeable misfire, but I just don't understand how changing the plugs to Laser Iridium and switching the coil packs around fixed the issue. I just took the car down to fill it with gas and came home and everything feels good. I haven't done a compression test yet, but will run one just so I can know where things stand.

Alright, so I just picked up a set of these and will try to install them tomorrow evening. I will do that and swap coils, and then it's time for compression test!

I actually bought the car in northern Vermont (near Burlington). When I got the title, there were 3 different people who owned it without registering it. They were all car dealerships, but I just thought that was weird. Seems to me like people would buy it, try to fix it, realize it was gonna cost them more than they wanted to spend and would sell it to the next sucker. The final one being me. LOL I admit, I hadn't done tons of research on the Legacy GT's. I knew they were fun to drive, and always wanted one, but foolishly bought the car without researching the forums. The first thing I noticed when I inspected the car was that it was missing the engine cover, and the hood prop clip was missing so it's just resting inside on top. If I knew what I know now, I could have had some serious bargaining power, but you live and you learn.

Thanks for the reply! Killington is right next to Rutland, so would be cool to have someone local. Yeah, I've been kicking myself for installing the Bosch coppers, but thought it'd be alright so long as I gapped them properly. I'll get a set of the NGK Laser Iridium's in the next couple days and replace them. So, say I end up repairing everything, and the codes all go away, what do I want to do for a tune? If I read correctly, the stock tune is what is causing some of the issues? I lived in Connecticut for a while (Litchfield), so I'm not afraid of making a trip / dealing with someone from down there.

I actually haven't changed the coils around yet, because it is supposedly a brand new coil pack on cylinder #2. Just for laughs though, I will swap them when I get a chance, just to rule it out, but I will then do like you say and run a compression test. I have a friend that has a well drilling business and has a garage / lift that I can use if it comes to having to pull the engine. However, I want to have all my ducks in a row because I can't tie up his garage for an extended period of time. I haven't looked for shops in the area, but living in Vermont I'm not sure what kind of luck I will have as far as "quality work" or a shop that "specializes" in EJ255's.

Hi, So I just bought a 2005 Subaru Legacy GT with 139,xxx miles on it. The place I bought it from said it was throwing a Cylinder #2 misfire, but that they changed the coil pack and it seemed to fix the problem. Well lo and behold, I was driving it 3 days later (approximately 150 miles since purchasing) and the check engine light comes on steady with flashing cruise control light. Since this is my first Subaru I didn't know what that meant, but soon learned that it was a type of "limp mode". I brought it to AutoZone and and they plugged the code reader in and it again showed Cylinder #2 misfire. Alright, well then let me buy some spark plugs and change them. I decided to go with Bosch Super Plus copper plugs even though OEM called for Laser Iridium (since I don't mind changing the plugs more often). This was my first spark plug job, but thankfully for this forum I found a few threads on changing them and was able to change them no problem! One thing to note, cylinder #1,#3, and #4 all had NGK plugs, whereas cylinder #2 was an AutoLite. Didn't really think much of it at the time, but I now have a theory of why that was the case. As an aside, I did make sure to gap the plugs to 0.044". I inspected the coil packs and sure enough cylinder #2 had a new coil pack, and the other three looked a bit rusted, but nothing terrible (and no codes) so I just reused them after applying some dielectric grease. So I put everything back together, and since my battery was disconnected for several hours it reset the codes and nothing popped up right away. I figured that I needed to drive a certain number of miles to have a drive cycle the computer could analyze, but I could tell there was a misfire. I went to the local GM dealership and bought a can of BG44K injector cleaner hoping that by some miracle it would clean things up and my misfire would go away, but at ~200 miles the check engine light came on with the blinking cruise. I decided to go and purchase a code reader (even though supposedly this car can show the codes on dash) I just couldn't easily find the green/white connectors under the dash, and decided that it would be handy to have a OBDII reader around. I plugged in the reader and sure enough cylinder #2 misfire! So my next step was to change injectors. I swapped #1 and #2 injector hoping for the misfire to follow, but nothing. Code reader showed pending cylinder #2 misfire. Although, I will admit the car ran noticeably rougher at idle, so I swapped the injectors back to their original position. I've been doing a lot of reading on the forum here, and I'm pretty scared of what the diagnosis might be. I mean, I guess I won't know for sure until I bring it somewhere, but I don't have lots of money and need to save as much money as possible. Am I correct in thinking it's a burnt exhaust valve? I just don't understand how I was able to drive the car home from the place I bought it from and not feel a misfire. The car pulled good, and had no signs of misfire. What should my next step be? Compression test?
