Hendrik Posted April 23, 2008 Share Posted April 23, 2008 I spend quite some time in trying to solve a rather uncommon problem. One week ago I mentioned it in http://www.ultimatesubaru.org/forum/showthread.php?t=87641 (Impreza , 1993 , 1,8l) First cleaned the rails and injectors by putting some cleaning liquid. I think this was my first mistake. Took out the left and right front injectors and interchanged them. I think this was my second mistake.... Question : Why is there a sticker on the two rows with R and L ? Are left and right not identical ? 3 out of 4 injectors do have a resistance between 11 and 15 ohm , which is the spec. The one originally placed left has 6,8 ohm... And I guess that this one is now always open , taken out the plug and rotating the engine results in fountains of gas. Once in a while the engine runs on 4 cilinders , mostly just 3. Then the search for parts : in the country I am , no change. Subaru dealers exist but helping service is negative. Ordered 4 in the USA , hope to get these soon. (and I hope the right ones....) Most online shops do not ship outside the USA. Ebay is mostly better , but what is the right injector for me? The ones which are now installed are pink , but there are grey ones , yellow , red and more....All seem the same in terms of size ... Question : Is it the amount of gas per millisecond who goes trough it ? I found some references but are these correct ? Partnr. FJ445 or 16611AA300 or 2320916120 .............. Last Question : is there some emergency manner for fixing the wrong injector ? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 23, 2008 Share Posted April 23, 2008 Where is the R & L sticker? Is it on the injector itself, or is it on the fuel rail? On the first gen legacies 90-94, the fuel rails are left & right specific, however injectors should not be left/right or cylinder specific. Is your 93 Impreza a US spec vehicle? From the info I've found and the parts book, the part # you want is 16611AA300 Josh Quote Link to comment Share on other sites More sharing options...
Hendrik Posted April 23, 2008 Author Share Posted April 23, 2008 Where is the R & L sticker? Is it on the injector itself, or is it on the fuel rail?Josh It is on the fuel rail , one sticker on one end only. In fact NOT on the rail , but on the pieces , who hold the individual injectors in place. Each with the 2 screws. On the first gen legacies 90-94, the fuel rails are left & right specific, however injectors should not be left/right or cylinder specific. Is your 93 Impreza a US spec vehicle? I don't know for sure if it is yes or no , the vin is : JF1GF6LR5PG010513 , it was sold via on official dealer in Brazil. From the info I've found and the parts book, the part # you want is 16611AA300 That is also the number I did transfer to the seller , I hope for the best.... Thanks...

Legacy777 Posted April 24, 2008 Share Posted April 24, 2008 The parts with the R & L stickers are considered the fuel rail. They hold the injectors and are mounted to the intake manifold. The reason they are R & L specific is because the rear fitting one the R fuel rail is different so that the fuel pressure regulator can bolt to it. The L fuel rail just has the fuel lines connected to it. I think you'll be good with what you ordered. Josh Quote Link to comment Share on other sites More sharing options...

Josh Just some follow-up , the USA ordered parts did not yet arrive (there is some Brazil customs strike going on) , but I managed to get one injector (used) injector for bare gold , in this country. Now it is behaving like it did never before , for sure this faulty injector did cost me a lot of gas...The engine is like new..... The last miles with the faulty injector was about 1liter/Km , or 2MPG... I did a change of the oil afterward , very high level , and of course mixed with gas. Oil was like water.... But as I said , already one year ago this injector did strange things , now this becomes clear. It might not happen very often , therefore I changed everything before which everybody thinks first ,(filters , plugs , etc) but do not forget the injectors , that is the lesson I learned.... Thanks for the advices , Harry Quote Link to comment Share on other sites More sharing options...
bulwnkl Posted May 2, 2008 Share Posted May 2, 2008 I'm glad you found the problem, Harry. You might be well advised to change the oil again in a couple hundred miles (or less). There will still be enough fuel in the engine to destroy the new oil you just put in. Quote Link to comment Share on other sites More sharing options...
