desdinova Posted November 14, 2007 Share Posted November 14, 2007 I have an 81 hatchback. the o2 sensor in mine looks like a spark plug with no pigtail coming out of it. the wire that connects to it looks exactly like a spark plug wire and has a two blade quick connect at the other end. all the parts houses show a single wire replacement when they put my make and model in the computer. Dosen't anyone make an exact replacement for mine. the subaru dealership said they are no longer made and there are none in any warehouses that he has connections to. I don't want to cut and splice my original wires if I don't have to, and like I said, they show a one wire and mine has two. surely someone has replaced one of these before, any advice would be appreciated.

GeneralDisorder Posted November 14, 2007 Share Posted November 14, 2007 No - no one makes them anymore. You will have to splice in a single wire sensor. The second wire on yours is the ground. All new units ground through the exhaust. Just eliminate the ground wire from your setup. What's your problem with splicing? Solder and heat shrink it if you want it to be professional. There's no reason to be scared of doing a little wiring. I'm a generator tech. and I do wireing all day long. Sometimes things change - you have to change the way wireing hooks up to stuff. Just the other day I replaced a main 3-phase breaker in a Generac and had to change the wires from hex-clamp to bolted lug.... no big deal. Siemens had superceded my part with a new model. Happens all the time. It's sad that you are still using the feedback carb though - get rid of it. Then you don't need to bother with the silly sensors. Put on a Weber, you will be much happier - trust me on this - I've been round and round this tree many times. GD Link to comment Share on other sites More sharing options...
desdinova Posted November 14, 2007 Author Share Posted November 14, 2007 I'm not scared of anything. I love my little Roo and would like to keep it as original as possible. What's wrong with that? I'll splice it tomorrow. When I peel back the plastic on the wiring, which color is the ground? And lastly I would love a Weber cept I don't have $350 dollars to be spending on myself, especially this close to the holidays. I'll eventually get one but it's not "sad" that I'm trying to make do until I can afford it. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 14, 2007 Share Posted November 14, 2007 I'm not scared of anything. I love my little Roo and would like to keep it as original as possible. What's wrong with that? For starters - it's not possible anymore, and you are are polishing a turd so-to-speak. The car is worthless as cars go, and will never be worth anything to speak of. Sure it's a fine car, but that's ALL it is. Make it the best car it can be, but don't kid yourself about "keeping it stock". You are worrying about tiny, tiny details when you should just be happy it's still on the road with that scandal of a carb on it. You may love it, but that doesn't mean it was well designed or even designed for the right reasons. If you REALLY love it, then do the SPFI swap - I've done all the work for you: http://home.comcast.net/~trilinear/EA81_SPFI.html And if you REALLY, REALLY love it, rip out the underpowered EA81 and put in an EJ22. Or just buy a Legacy - gaurantee you'll love it more When I peel back the plastic on the wiring, which color is the ground? No idea - whichever one shows continuity with ground. And lastly I would love a Weber cept I don't have $350 dollars to be spending on myself, especially this close to the holidays. I'll eventually get one but it's not "sad" that I'm trying to make do until I can afford it. Make due by spending that $40 on a used non-feedback Hitachi then. Don't throw away money on O2 sensors. Or just run with the O2 disconnected - it really won't make that much difference. The feedback system at this point is so old it may not really function much at all anymore. Not that it did a whole lot to begin with other than make mechanics very angry GD Link to comment Share on other sites More sharing options...
desdinova Posted November 14, 2007 Author Share Posted November 14, 2007 You really ARE an rump roast aren't you? That's okay, I like your frankness and appreciate your time and effort on my behalf. Thank you. I looked at you spfi link. Man that's intimidating. I'll leave it disconnected till I afford a weber. Thanks again sparky. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 14, 2007 Share Posted November 14, 2007 You really ARE an rump roast aren't you? Yep That's okay, I like your frankness and appreciate your time and effort on my behalf. Thank you. I looked at you spfi link. Man that's intimidating. It's really not that bad once you get started. Understanding how both the carbs, and the SPFI operates - the principles behind it - are what make it doable. I suppose that's why so few have done it - despite me and Snowman both attempting to make it more accesible to the community. I'll leave it disconnected till I afford a weber. Thanks again sparky. Yeah - probably not a bad idea. At this point the duty solenoids are probably shot anyway. And tuning new ones would take an o-scope and the '81 FSM..... and probably a week of your life you would never get back. Not to mention the cost would be more than a Weber for the parts needed to make it all function. For what? 1 mpg?? That's all the CA feedback models got over the non-feedback versions.
