subyfreak Posted November 18, 2007 Share Posted November 18, 2007 I have a 91 Legacy Turbo that I think needs a injector. It will idle fine sometimes but under load it runs on 3cylndrs. It is getting spark and when it is running rough if I disconnect the #2 injector wires it makes no differance. The question. Is the non-turbo legacy injector of the same year the same as a the turbo injector in my 91? There are no turbo legacy parts around here but plenty of non-turbos. Thanks for the help Link to comment Share on other sites More sharing options...
bulwnkl Posted November 18, 2007 Share Posted November 18, 2007 Can't answer your question, but may have a helpful suggestion. Try to locate a fuel injection repair shop (usually they advertize to the heavy diesel industry) and see if they can rebuild it for you (they can test them, too). A rebuild is not always possible/helpful with electronic fuel injectors depending upon what's wrong, but often is. I had a shop in Boise rebuild my '91 XT-6's injectors. No problems and something like $20-25 each, IIRC. Link to comment Share on other sites More sharing options...
ericem Posted November 19, 2007 Share Posted November 19, 2007 No they are not. A turbo engine would have a higher flow injector. Have you check the spark plugs? Link to comment Share on other sites More sharing options...
subyfreak Posted November 21, 2007 Author Share Posted November 21, 2007 Thanks for the advice. I just changed the plugs, wires, and fuel filter and still no differance. The cheapest turbo fuel injector I can find is around $85. I will see if anyone around here can clean one. If any one else has some ideas on why my car runs like this please post it.

frag Posted November 21, 2007 Share Posted November 21, 2007 Thanks for the advice. I just changed the plugs, wires, and fuel filter and still no differance. The cheapest turbo fuel injector I can find is around $85. I will see if anyone around here can clean one. If any one else has some ideas on why my car runs like this please post it. Just to be sure it's the injector, I would make a swap and see if the problem migrates with the injector. Nothing was also happening when I disconnected injector no 2 on my car but the exhaust valve was the culprit. Good luck! Link to comment Share on other sites More sharing options...
Reveeen Posted November 21, 2007 Share Posted November 21, 2007 +1 on moving the injector to another location (make sure you have replacement "O" rings and manifold seal on hand, 2 O rings per injector, 1 seal) O rings- 16698-aa030 Seal- 16608-aa020 Beck-Arnley offers rebuilt injectors, best price here is $62, wait 1 month.

rverdoold Posted November 21, 2007 Share Posted November 21, 2007 never thought they were that expensive. I had 4 of them from a 92 turbo to try in the non-turbo there was some power increase but not in line with the milage which went down the hill very fast. Whats the milage on the car? working times = (milage*t)*Delta RPM guess t is 1 minute per mile on average Delta RPM is lets say 2500 RPM so milage * 2500 = injected times and devide the price of the injector by this number and see how much it costs per injection not included the fuel though. Sorry for the wednesday evening math, wished could help you further sorry to say sold those ones for 50 euro each. Link to comment Share on other sites More sharing options...
tcspeer Posted November 22, 2007 Share Posted November 22, 2007 I would buy a set of noid lights and check and make sure the injector is getting the signal to operate. You can get these for around 15.00 dollars at Auto stores. When my number three injector quit working it was the fault of the computer, I had current to the hot wire of the injector but no signal from the computer to make the noid light flash. After replacing the E.C.U. the problem was fixed. Link to comment Share on other sites More sharing options...
subyfreak Posted November 22, 2007 Author Share Posted November 22, 2007 say it is the ecu can a non turbo ecu be used? Link to comment Share on other sites More sharing options...
tcspeer Posted November 22, 2007 Share Posted November 22, 2007 I think their is a number on the unit that must match, if someone here dont know you may be able to find out from the dealer. say it is the ecu can a non turbo ecu be used? Link to comment Share on other sites More sharing options...
Manarius Posted November 22, 2007 Share Posted November 22, 2007 Are you sure it's not the coil pack? Did you try another one? Link to comment Share on other sites More sharing options...
subyfreak Posted November 25, 2007 Author Share Posted November 25, 2007 I have a non turbo coil pack that I will try. There is a slight difference in design but they both have the same connector. While driving the car today to get some fresh fuel and injector cleaner through it the cel came on. I will check it out when I swap the coil packs. Thanks again.

subyfreak Posted November 26, 2007 Author Share Posted November 26, 2007 Here is the list of codes that flashed when I connected the black diag. wires. 13 cam angle sensor 14 injector #1 15 injector #2 17 injector #4 21 water temp sensor 22 knock sensor 23 air flow sensor 42 idle switch Is this possible? And the car still runs. Thinking possible ecm problems now. Any way to confirm this? Link to comment Share on other sites More sharing options...
subyfreak Posted November 26, 2007 Author Share Posted November 26, 2007 I pulled the neg. battery cable for about 30min to clear the codes. While I was waiting I traded the coil pack and plug wires with my 92 Legacy. After hooking up the battery I started the car and let it idle for 15min. No problems running great. Took it for a drive and after about 5min of driving it starts missing when I get into it a little. after 10min of driving it is missing more than not. Get it home and it is idleing rough. No cel light the whole time. Any ideas now? Link to comment Share on other sites More sharing options...
ericem Posted November 27, 2007 Share Posted November 27, 2007 Electrical problem. Maybe it's a ground issue? Or the ECM itself. Link to comment Share on other sites More sharing options...
subyfreak Posted November 28, 2007 Author Share Posted November 28, 2007 I don't really know much about the history on this car. I saved it from the junk yard for $200.00 and drove it home. It needed ball-joints and a rear CV-shaft and some cosmetic work so with 200000 miles on it I figured the previous owner just wanted something newer and there would not be this much wrong with it. My bad. I can see the potential in the car and still think it is worth saving. It is still really solid where it needs to be (pretty rare up in the salt belt!) and I like having something different. Although I will pay the price for parts! There is a guy around here that works on nothing but Subaru so I will take it to him and have him check it out. Thanks again for all of your help it's nice to have a place where all of us can go for help. Link to comment Share on other sites More sharing options...
ericem Posted November 28, 2007 Share Posted November 28, 2007 Ya who knows might turn out to be something simple. Definitely worth it to spend money on the car if it runs fine. For $200 its a steal especially if it has the EJ22T. Link to comment Share on other sites More sharing options...
subyfreak Posted November 28, 2007 Author Share Posted November 28, 2007 Thats what I was thinking. If anything I can always use more parts since I will always have a Subaru or three. Link to comment Share on other sites More sharing options...
