Well it sounds like you've replaced all if not all the common components that I think that would cause a miss. Can you describe the miss in more detail. Is it a long pause, or just a short pause? Does the miss repeat more than a couple times in a row....details like that. Only thing else I can suggest is to check all the wiring from the sensors to the ECU. There may be a wire that is worn and may have intermittant connectivity when the engine heats up. My mom had a similar issue with her 90 Toyota truck. The engine wiring harness had an issue with one of the wires where it would cause the engine to shut off. It was heat dependent.

Bry, I've got a 97 Impreza Outback Sport and yes the AC compressor clutch is noticable. It's normal. The AC systems do have expansion valves and function the same way as others. However, like I mentioned, I think some manufacturers use less expensive components and control systems than others, which causes more noticable cycling and temperature swings.

For the most part it sounds like your AC system is working properly. Your refrigerent charge may be off a little bit, but without a full set of gauges to determine pressures and temps, it's a little hard to say. The reason your compressor is cycling when on recirc is because the incoming air is already "sufficiently" cool and tells the thermo switch to cut off the compressor. When the temp increases, compressors kicks back on, and the cycle repeats. If the incoming air is always warm, then the thermo switch doesn't kick off. What I have found is that some cars don't have as good of a control system and as a result the temperature swings between when the compressor kicks off and on are greater. Additionally, compressor design will affect this as well. The older legacies 90-94 had a variable geometry compressor. So instead of cycling, they would alter the compression ratio internal and allow for less refrigerent to flow to the evaporator which would help moderate temperatures. IMO, this system is superior in terms of keeping a more constant temperature. The downside is the compressors tend to be more complex and may have a more likely chance of failure. Not sure if I answered your question....if not let me know.

Dan, The problem is likely the speed sensor if the 95 legacy has the electronic speed sensor. If it still has the cable going from the transmission to the gauge cluster, the culprit is likely the base piece that connects to the transmission. http://www.main.experiencetherave.com/subaru/images/speedocablebase.jpg

Welcome to the USMB. You will likely have to get the thermister from the subaru dealer. You may also be able to find one used from someone either on here or the legacycentral bbs who has a parts car. Or if you have a junkyard near you, you may want to see if they have any legacies you could scavenge. I'd suggest checking out the legacycentral bbs, as there's a lot of stuff over there, and likely a member who has a spare car they could snag the thermister from. http://www.bbs.legacycentral.org

Jeremy, The shifter not moving out of park without pushing the button at the top is a result of shift lock system not functioning correctly. Typically, the solenoid below the shifter assembly may be bad and not releasing the shifter. The other possibility is that brake switch is bad. I'd suggest testing the solenoid. It should click when you depress the brake pedal. You can apply 12v to one lead of the solenoid and a ground wire to the other lead going to the solenoid, and it will engage the solenoid. If the solenoid doesn't engage, then you know it's bad and needs to be replaced. As for the clunking, it's kind of hard to diagnose without a little more information. Can you tell where the noise is coming from?
