yellow82glf Posted February 15, 2017 Share Posted February 15, 2017 so I picked up a pair or 82 glfs for a couple hundred bucks. figured it work as a great commuter. 5 speed ea81. 109k miles. I don't think a part was ever changed on it. after a bunch of mishaps and swapping of my ea81 engines I needed to get the title. which here means smog. out of the system with 0 paperwork. these cars were on the local Subaru lot before it went out of business and sat for 15 years. with a smog OK sticker in the window. should be a simple smog? not so far... so far I'm trying to figure out the point of the o2 sensor to the cat, it's a 2 wire, beings the car is fairly mechanical what does it do? i pulled it out and it's like the idea of a spark plug and wire? my temp sensor is a 2 wire. all these lead me to believe California emissions equip. I'm having standard issues with the hitachi, ran great after rebuild. now secondaries are not functioning. and it likes to stick the butterfly open to hold 1200 rpm.and the mixture screw all the way in. I'm going to rebuild the better of the 2 carbs again. the high idle switch has stopped working, before I messed with the o2 the idle would go up with ac on. after o2 it worked for heater and ac. never on start up with this carb. now not working at all unless bypassed. does anyone know what controls the high idle switch? if I run a hot wire I can make it create the vacuum it needs Quote Link to comment Share on other sites More sharing options...
DaveT Posted February 15, 2017 Share Posted February 15, 2017 I am not familiar with that specific year model. Going by what I know from the SPFI EA82s the O2 sensor should have no effect until the engine e is close to normal operating temperature. Double checking everything in the carb seems like a good idea. Also, whatever system is used to control emissions related stuff. Test any switches and sensors and solenoids etc. Quote Link to comment Share on other sites More sharing options...
skishop69 Posted February 15, 2017 Share Posted February 15, 2017 There is a mixture control solenoid inside the carb that is controlled by the ECU based on the O2 readings once it warms up and goes into closed loop. You have to make sure you have a carb with this solenoid or it won't pass Ca emissions. I'll check schematics later for the ECT sensor.

yellow82glf Posted February 15, 2017 Author Share Posted February 15, 2017 that would make sense! I was wondering the job of that solenoid. probably why I was getting too much fuel last time I went, and was smelling it once it warmed up. I ran an aftermarket temp gauge, taking the old sensor out of the loop. because the stock one was not working. after I have gone back to the stock sensor thinking it had something to do with the o2. and just like that the stock temp gauge came alive. that's when I started noticing my new carb issues. kit is on its way. and I'll give her another shot at the smog. thanks guys!

yellow82glf Posted February 18, 2017 Author Share Posted February 18, 2017 is there any site that sells new parts for the hitachi? I can get the carb kit from rock auto. but how about the secondary diaphragm ect.. Quote Link to comment Share on other sites More sharing options...
