tcspeer Posted January 3, 2006 Share Posted January 3, 2006 Get you an in line plug checker and see if you are getting fire, they can be had for a few dollars at part store. If you are getting fire check to see if the inj. is clicking, if it is clicking get you a noid light and check the inj. plug,you can get a set of these also for a few dollars. If this light dont light then then you will need to check to see if it has fire coming to it, use a small test light or mutimeter. If you have current here it could be the E.C.M. that was what was wrong with mine when I had a #3 misfire code. Did you check the easy stuff first like the wire and the plug? I had current to my inj. plug but it was not getting the signal from the E.C.M. to do what it was suppose to do. Link to comment Share on other sites More sharing options...

tcspeer Posted January 4, 2006 Share Posted January 4, 2006 If you go to a mom and pop auto store you can probably buy just one plug wire and change it, also buy a plug this may take care of it with out all of the other tests. Link to comment Share on other sites More sharing options...
idosubaru Posted January 4, 2006 Share Posted January 4, 2006 tapper, i'd replace all the spark plug wires. i would not use one from the auto parts stores on the newer subaru's. i've had bad luck with them on my OBS. bought one to use while i waited for mine to come in the mail. ran like crap and didn't clear the code even with a new generic one from the store! i'd use OEM Subaru wires or magnecor (that's what i have). newer subaru engine wires are tricky and have issues seating properly. they are not as forgiving as the older soobs. you might want to start checking all your spark plug boot connections and look for anywhere the boot may be compromised. the plug itself could be to blame as well.

tcspeer Posted January 5, 2006 Share Posted January 5, 2006 Your right about after market wires we had an issue with this when replacing some on a Saturn. I now keep my old wires when I take them off that way their is one if I have one that gives trouble. tapper, i'd replace all the spark plug wires. i would not use one from the auto parts stores on the newer subaru's. i've had bad luck with them on my OBS. bought one to use while i waited for mine to come in the mail. ran like crap and didn't clear the code even with a new generic one from the store! i'd use OEM Subaru wires or magnecor (that's what i have). newer subaru engine wires are tricky and have issues seating properly. they are not as forgiving as the older soobs. you might want to start checking all your spark plug boot connections and look for anywhere the boot may be compromised. the plug itself could be to blame as well.
