Wow, that was really helpful. That makes a lot of sense. Thanks for the write up

So I just pluged my #2 injector back in and I have tons more power and it seems to only miss and trip a flashing check engine code when I idling. If I give a tiny bit of gas the blinking stops. So Im guessing that when I'm idling its not firing correctly and pumping that unburnt gas in the cat. Give it a little gas and all is fine. So just by guessing that would mean that the O2 works because its reading the extra fuel, its getting enough gas because it triggers the blinking light which means its damaging the cat with extra fuel. Car still runs great except the tiny misfire at idle. This is so confusing. Will a coil from a 2003 subaru legacy work on my 97 outback? Just to test if it makes a difference

I can get a EJ2.2 with less than 40k on it for $1,300. After putting new T-belt and gaskets on her I would say around $1,700 for a good low mile engine is a good deal. Not doing the 2.0 NA or 2.0 Turbo

just did the doller bill trick with the exhaust. Pretty sure its a burnt valve. Well I guess we will see how long this EJ25 with 251k, a burnt valve and running on 3 cylinders last. Any bets? After she blows it will be a 2.2

I have not changed the wires and coil yet. I know the coil is old. Its also missing a bolt on the side of the misfire. Not sure if that would do anything. I'm gussing valve damage. I have the injector unpluged right now and it makes a whistling noise out of the tailpipe when I give it gas. Not sure if its a sucking noise from a burnt valve.

So I unpluged the #2 Cylinder Fuel Injector and the flashing check engine light went away. Still acts the same, #2 Cylinder is missing. So I'm guessing that 1. my o2 is working to detect that I wasnt dumping fuel in the cat anymore causing the blinking check engine light. 2. my problem is likely no spark or weak spark or mecanical in cylinder #2. I probably clean the EGR Valve and the Mass Air Flow today or tommorw just to see if it makes a difference. Anymore ideals anyone?

I checked the Plug Wires by switching them, Didnt seem to make a difference. I dont have a Multmeter or anything to read the resistance on the coil. I did unplug the the #2 wire from the coil and it seemed to have spark. I also unpluged the front O2, drove it around for about 15- 20 mins and it acted the same, no difference. The CEL still was blinking when idling. Truth be told I bought this car for super cheep from a friend because he bought a new Sub and never drove it the old 97. I got it for $250, its in pretty good shape but has 251k on the clock. It really runs pretty good besides the misfire. I really just want to use it as a winter beater but it would be nice to fix this misfire as cheep as possible. I'm not opposed to getting new basic parts if it needs replaced and stops the misfire. But if its anything internal I would rather just put in a 2.2 or a 2.0 because that would really be cheeper in the long run. Can I clean the Cat and O2 to see if that would make a difference before forking out $$$ to replace them. I have a 2003 Outback that my wife drives and a 2005 Outback that I can drive also so the 97 Outback doesnt have to be perfect. Dont know if any of that made sense.

Hello all, I have a 1997 Subaru Legacy Outback and I'm having a P0302 Misfire. Ive just checked the spark plugs and wires and they both seem good. I replaced the plugs also because why not. No change. My check engine light is flashed only when idling and warmed up. Give it some gas and it will go away. Ive tried to find a vacuume leak via carb cleaner, Nothing. Changed Plugs, Nothing. Checked Wires, Nothing. Took it to a shop and they said it could be a clogged Cat or O2 Sensor. Will a bad front O2 sensor or clogged cat trip a flashing CEL/ Misfire on just one cylinder. Any suggestions would help, not trying to replace everything just to find the problem.
