Question about 1997 Subaru Legacy

How do you replace the spark plug wires on 1997 Subaru outback/legacy?

I need to replace the spark plug wires on my 1997 Subaru outback/legacy. I've looked it over and it seems like it would be easy. It's just that the engine is built much different than other cars I have seen. From what I have read, I might not be able to simply take out the spark plugs without a jack of some sort. Can I access the spark plugs form the top or is it easier to replace them from underneath the car?

Access from top is better but you must remove battery/washer reservoir driver's side and intake piping on passenger's side to get to the plugs. If you have bad back, access from underneath is fine but I'd have a ramp instead of jack for safety reasons.

SOURCE: Subaru Engine Vibration

I'd suspect a vacuum leak in the inlet manifold, check to see if any vacuum lines might have fallen off. This can cause a lean misfire at idle, but often it's not enough of a leak to make it lean enough to misfire at higher rpm. If a leak is not obvious, check if it is a leak by buying a can of engine start (or even CRC will do) and spray it all around the inlet manifold. If the idle smooths out while you're spraying then then goes rough again, it is a leak. By spraying in specific areas you can narrow down the area of the manifold or gasket that is leaking.

Hope this helps.

SOURCE: Not as easy to change as any of my other cars. Do I have to remove the motor mount?

Not easy without proper plug wrench. If not available then I use a plug socket and 1 " extension. Reach them in first onto the plug, then put ratchet on. When I re install I use a small piece of hose that the plug sets in to start the treads. The hose won't allow you to get enough torque to strip the threads but will start. Good luck and try to have paitience.

when you replaced the plugs , was one of them (cylinder 1 ) dirty and fouled ?
I'm thinking that bad rings in cylinder would give you low compression , and eventualy cause the missfire by fouling up the plug.
There is an inexpensive product that will help with the compression by filling up scratches in the cylinder walls. It is called Restore , and it is one of the only products of its type that I have used , and feel actually works.
Unfortunately , if your rings are broken , or badly worn , nothing in a bottle will fix them.

If your car had a distributor cap and rotor , I would change them too.

Is a rear diff from a 1997 subaru legacy wagen with a 2.2l inter changeable with a 1997 subaru legacy outback with a 2.5l ?


the only way you can do this is if you can identify the gear ratios from both cars with the transmission codes found on the strut tower plate.
see this list to check for matches, read it carefully its a ton of info

Can you switch a rear diff from a 1997 subaru legacy wagen with a 2.2l inter changeable with a 1997 subaru legacy outback with a 2.5l ?


the biggest draw back that you will have to check first is the ratio of the diffs you want to change. If they are not the same but will fit then you will destroy the 3rd diff in the transmission from excessive use.

Just changed the plugs and wires, in my 1997 Subaru Outback legacy 2.5, and the car starts up and then runs rough for about 3-5 seconds and then shuts down, I bought after market wires, and they are not...


Thanks for choosing FixYa and welcome to the site. This is very well possible. If the plug wires are in the wrong spot, it will cause this. Make sure that the spark plugs were gapped correctly as well. Most plugs come pregapped but just make sure. Check for any wires or hoses that may be loose from changing the plugs. Make sure everything is put back on. When you change plug wires, make sure you mark them. I would double check the plug wires. If you didn't have this issue until you changed them, more then likely, that is whats wrong. If you have any questions, feel free to ask and thanks for using FixYa.

My `1997 Subaru legacy outback wagon ,my gas mileage went from 21 MPH to 15 MPH. What do you think is wrong.


if there are no major problems present all it needs is a tune up(spark plugs,fule filter,oil change, air filter, fule injector cleaner). for a upgrade in fuel economy add a short ram intake, parts are fairly easy to install.

I have 1997 subaru outback wagon that I bought used. It appears that the spark plugs and wires are still the oem wires and have never been changed. How do I get a broken plug cover off to remove the plug?


As you are going to replace the plug and wire anywhere, get a pair of needle-nose pliers and grab what's left of the broken plug wire and pull hard. Even if it snaps the spark plug off, you will still be able to use the spark plug socket to remove the plug.

1997 subaru, starter would not engage when hot,


You need to make sure that the grounds for the body and motor are good. Sometimes just turning the bolt will clean them up but better to remove, clean and replace. Also make sure battery terminals and wires are clean and secure. Hope this helps and have a great day.

1997 legacy outback 2.5 will turn over but will not start. replaced timing belt, plugs, wires and crank sensor. has spark, new battery and fuel pump works. what's the next area to focus on.


****,squeeze, bang, Blow. That is what is required for a motor to operate. If you are getting fuel and current for the bang then the only thing left is the squeeze and blow which would be your compression. Have to make sure that the timing belt was timed properly to operate the valves to allow for compression. Hope this helps and have a good day.

Cause of noise in front differential of 1997 Subaru Legacy Outback.


there is a plug on the shaft-side of the differential. Using a ratchet remove the plug and with the engine OFF, stick your finger inside the hole and you should get fluid just below the threads of where the plug goes in.
