Question about Subaru Legacy

1 Answer

Hi, I have a 1995 Subaru Legacy estate, 73,000 miles on the clock. It is the imported (to the UK) Boxer 2-stage twin turbo, (my second one in a row!). Problem is that i thas a drop in power occasionally. Usually at around 2100 revs but not every time. I can be driving at 30mph or 60mph, at a constant speed or accelerating. A couple of time the 'Check Engine' light has come on for a second before going out. Oil, water etc are good. What can it be? I haven't run it into a garage for a diagnostic yet. One of your collegues suggested a loose or split hose allowing air into the manifold but there are so many hosed under the bonnet I have no idea where to look first!

    Hi, Thanks for the advise, We don't have AutoZone in the UK but I will try and get it in somewhere tomorrow for a fault code. Mostly it drives lovely so i hope it's nothing too scarey! Mechanics I've spoken to in the past seem to consider these well put together and reliable. I'll get back to you with the code as soon as i have it... will my car have a conector for the diagnostic computer? Thanks.

    Hi, Took the car to a local grage that specialises in Subarus and they hook it up to their diagnostic computer and said it is the knock sensor. I have another car the same at the moment thats has a cooked engine si I'm going to take the knock senor off that and have them fit it and re-set the ECU. That'll sort it out, thanks for your help.

I am sorry to Hear Regarding the Problem. This Model is Prone to Many problems. If Check Engine Light is ON, and you have Driveability issues, i would Advise you to take the Car to Auto Zone and get it Scanned. There is No Point in wasting your Time, if you could get the Diagnostic Code. I have hardly seen Hose Problems in this Car. Frankly, Auto Zone and there are so many Places where you could get a Free Diagnostic Code. Take a print and let me know. Whenever there is a Driveability problem and you see check Engine Light Flashes, more often this is an Indication, that there is a Serious problem with the Car and the Error is stored in the Memory of the Car Computer.

Read :-

If there would be No Error Codes, then we need to Check all Wiring and other Stuff which would be time Consuming. But, if we could get the codes, that would tell us the Reason and then we could easily track the Problem.

Let me know,once you have the Car Diagnosed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    I would be waiting for an Update. Regarding Connector, there are different ways to Find Code. Few do not need any Connector. Few does need that.There are Connectors on this Model.There are Different Locations. It depends on which Software and Scanner would be used to read code.

    Let me know,once you have the Car Diagnosed.

    Hope i helped you.

    for using ' Fixya ' and have a nice day!!

Hi, car Is a 1995 manual gear box, Subaru Legacy GT Estate car, petrol r/h drive (UK), 2L twin turbo that was imported into UK. clutch pedal began to stick in the pressed down position occasionally so I...

Hi these clutches are actually hyraulic so first id check the oil in the clutch bowl container under the bonnet on the drivers side if you havent already, secondly you can adjust the clutch slightly under the inside of car on the pedal it has a nut you remove then just turn the thread to suit you cant miss it really, however i would be more inclined to think your problem is the clutch slave cylinder on the side of gearbox it would cause this problem when worn as oil leaks past. To locate it just look on passenger side of gearbox and follow the hydraulic hose, they are easy to replace (just unbolt) and not too expensive.

I have a subaru legacy 1995 estate, it's the boxer twin turbo and I can't get the reversing lights to work that are on the tailgate. I have checked the fuse (wording on the box all in *** but I have a...

The switch is call backup light switch.

Inspect / clean the entire unit end to end.

Spray WD-40 or similar fluid on the plastic male and female socket ends to rule out bad contact points.

You may use a meter to check the socket for conductive resistance (when pressed)

I attached two pictures to help you identify the plastic socket that you need to disconnect and clean.
UK/International switch may look sightly different from USA version.

Remove / adjust this switch on level ground.
Transmission/gear fluid will leak out during removal.
Top off / inspect all fluid level after switch installation.

This backup switch retail for around $45 USD.

Good luck

Hi, I have a '95 2L Legacy Boxer 2 stage twin Turbo. When i'm driving and the engines reving at ot just above 2000 rpm I'm getting a dip in power for a moment before it picks up again. I haven't noticed...

the 1st thing that needs to be done here is to find what fault code is turning on the check engine light, this information is absolutely crucial to making an accurate diagnosis of this problem, guessing is not an option as each part that could cause this is very hard to replace and very expensive, so get the the engine control system tested, this is what is called OBD 1 electronic engine control and requires a Subaru scanner to read code.

Fault code 45- how do i repair it?

The code 45 in a later model is for the AWD control module causing harsh shifts. On a 2000 model the warranty per recall is 8 years and 100,000 miles. For your model you can try calling a dealer about recalls.

Sudden loss of power when travelling for a few seconds,

The spark plugs for your vehicle are located 2 on each side of the engine. They are a little difficult to get to because they are right by the frame. Follow the plug wires from the coil and you should have no problem finding them. Hope this helps Good luck.
