Just wanted to give a little update Sometimes when we have problems we automatically think of the worst possible scenario. But after hearing all of the calls for disaster on my 84 GL's hesitation problem... being told it was the feedback carb's fault, the code 14 being a disaster code and all that (just check the posts)... The whole problem was a severely clogged carb from having old gas sit in it for a long time. A couple fo sea foams, complete tune up, a berryman b12, some carb spray cleaner and presto!! The car has been running like a champ now for weeks, about 1000 miles of perfect running and 28.2 MPG (so much for that post that I would be lucky to get 15-20 MPG with the Code 14 on! Anyway have a nice day. Thank you all for the help. But one thing - just don't automatically assume the worst. :cool:

So probably the one that changes how the computer feedbacks to the carb the most is the O2 Maybe someone reading this would be kind enough to scan one for me I have 2WD but I'm not sure about the hitachi or carter. I thought that only hitachi was available that year. I'm trying to fix a problem with hesitation that comes and goes. The carb has 224+ k miles so it needs a rebuild. I also have the ignition pulse code (Code 14 that year), but I'm not sure how much that has to do with it since it was running for a few days perfectly even with that code on. I think it could be gummed up carb from sitting for years with old gas in it. I've only driven it 155 miles since its been sitting for that long, and it seems like if I spray a ton of carb clear in it and suffocate it sometimes it comes out of the problem for a while and but then returns to the same old stuff. I'm getting a rebuild kit through autozone today but I wanted to know what things could be effecting the feedback so I could replace those too. I don't want to go weber.

Do I have to remove the distributor to take out the control module? I took the cap and rotor off but there is a part above the module that is shaped kind of like a star that doesn't seem to come off. Any suggestions? 84 gl ea81

What is a duty solenoid? Also, are those the main factors (O2 + duty solenoids) that determine the feedback given to the carb?

Apparently I have a feedback carb and I am looking for what items impact the feedback on it. I suppose the O2 sensor is one of them

Couldn't I just rebuild the one I have then with a rebuild kit from a non feedback and take off the feedback equipment? I guess I don't understand the differences between the feedback and non feedback in this way ---- did the same model years (like my 1984 with this problem) come with the option of both feedback or non feedback? How could I determine which carb is which from looking at them at a salvage yard?

How can I tell?

Is it common for the ignition control modules to go out? I'm trying to find one for an 84 ea81 but they are rediculously expensive new and I don't have any place to get junk parts. Does anyone have one thats known to be good? How much would it cost for one of you guys to get a whole distrib from a junk yard?

Does anyone have a list of sensors on an 84 ea81? Thanks

I am starting to have my doubts if this code has anything to do with my problem as well. The two days that the thing was running great the ECS light was still coming on. What years had the non feedback carb that bolts on? I am going to call a salvage yard in my town to see if they would have it. Does it use the same air cleaner box? Thanks.

For anyone who has been reading my threads you know I have been trying to chase this problem down. For two days my 84 GL ran like a brand new car and today it suddenly began having all the sputtering probelms returning and so on. My next questions are these if anyone has a clue: 1. Could the ignition pulse problem be caused by the fact that my ignition coil is leaking a bit of oil? Could the coil be overheating? 2. Could the oxygen sensor be causing this ignition pulse code to come on and cause my problem? 3. Could the sensor with the vacuum lines connected to it in the air cleaner assembly be causing the problem? 4. Could the distributor or the control module be causing this problem? 5. Could the carb be so worn that it is throwing off the system to display this code? 6. Is there any way to get my hands on a factory service manual or find one scanned online? Thanks and if anyone else has had experience with the ignition pulse problem please let me know. I know I am beating this subject like a dead horse but this is my only vehicle right now while I'm paying my way through college and providing for my wife and 2 kids so I have a lot more time to stay up late and work with this thing than $$$ right now. I also don't really feel like exchanging this out to a weber either for $$$ reasons. Thanks for all the help

Does anyone know where I can find specific information on troubleshooting code 14? Is there a site that has info from the FSM? Thanks

Does anyone have a link to a good, step by step method of converting my 84 GL to a Webber or rejetting my Hitachi to non-feedback? I would need step by step instructions. What model Webber needs to be used? Do I need any kind of kit? What modifications are necessary? Thanks

When checking the engine codes, does the unit normally continue flashing the same code repeatedly? As stated in another post, the car seems to give me code 14, but it continuously flashes this code at least for the minute and a half that I watched it. Is it normal for it to continue with the same code?

Ok guys thanks for all your help so far. This is an update of my problem. I have currently changed both fuel filters, air filter, PCV valve, spark plug wires, distributer cap + rotor and the plugs look OK. I have changed all the vacuum lines that look terrible - I didn;t change the T connectors and I don't really want to buy another 15+ feet of vacuum line to do the rest if they don't look cracked. I have checked the engine code to the best of my ability I think it is code 14. According to the HAYNES computer control book, this Subaru code is "Duty Solenoid or Circuit (Fuel Control)" I have no idea what this code means. When driving the car it continues to have the hesitation when first taking off. It runs the worst at speeds from 35-55 mph. I brought it on the highway and brought it up to 80 MPH. It seemed to run great at the high speeds - no missing or surging that I could tell for the short time I had it that fast. The idle is still rough, sometimes stalls, also sometimes stalls when taking off if you dont pump the pedal. I checked the carb, it looks pretty worn out. I have ordered a rebuild kit and I'm wondering if that will solve the problem if it is the accelerator pump. Also does anyone know if the intake manifold gaskets are prone to going bad? I noticed some oil on the spark plug wire where it plugs into the coil. It looks like the coil could be leaking some oil. The strangest thing is that this car seemed to be running pretty much normal a few days before I put it on the road. I could drive it all around and it didn't seem to have these kinds of problems then! Very frustrating! It almost seems like all this stuff has just made it worse but its probably just my frustration. If you can help THANK YOU:burnout:

Thanks everybody for the help. The car ran yesterday horiibly missing! I could hardly get to work because it was bogging down and couldn't get to highway speed because of the misses. Strangely enough I went out to look at it on my break hour and messed with it a little bit with no results. It doesn't look like any vacuum lines are bad and I used some carb cleaner to clean the throat and sprayed around the outside to clean near the springs etc. It was still having the same problem THEN I was driving home that night and the problem VANISHED for about 3/4 of the trip home when it started to have the original problem but on a much smaller scale. I am an assistant manager at an auto parts store so I bought the secondary filter under the hood we have in stock just to see what will happen. If anyone has any other thoughts I appreciate the help!

Both? Are there two fuel filters on this vehicle?

You may have seen my other post for help regarding hesitation. I also have notivced, when checking the diff gear oil level yesterday, that it was bone dry. I filled it up but it seems to have a (hopefully) slow leak coming from the passenger's side near the CV axle. Is there any kind of gasket there or seal around the CV axle? Anyone know of something to slow that kind of leak? Is this common? Thanks.

Hi, I was just given a 1984 Subaru GL wagon with 1.8 Carb. I am having very random hesitation when coming from a stop. The car will go only if I press the gas pedal rapidly. IT has 224+k miles on it and has been very neglected. I have replaced the air filter, dist cap + rotor, done an oil change and refilled the diff (which was empty! ) since getting it yesterday. Any suggestions especially on something that has been so neglected? I am a capable DIY mechanic. I am not very familiar with Subarus however. ECS light is on also.
