Legacy777

Do you have all the screws off? If it's like the impreza, you just have to pull out, but hopefully someone else can confirm this or not.

check the codes before you do the battery. www.surrealmirage.com/subaru/trans.html

Yup....those are the correct pins.....The TPS resistance will be off a little bit....but those are pretty subtantial differences.....so i'm not sure.

The info I have confirms those service manual resistance values are what they should be. Here's the scan from the US subaru factory manual http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TPS_testing1.jpg Are you sure you're measuring the correct terminals?

I didn't recommend this because it can be a safety issue if you have small children or a lighter weight individual in the front seats. But yeah....it depends on how things are designed. Most of the new airbags are supposed to be "smart" airbags and deployment speed depends on the weight of the person.

Incorrect....OBD1 Legacies will give you nothing but problems if you don't have the VSS hooked up. I can't say why yours isn't giving you problems, but I have experienced it first hand as well as helped diagnose others with similar weird problems. Phizinza, you really need to find a way to get a VSS to the ECU.

AT or MT? Replace the CV axle and fix any other items you found to be broken, then see if you still have the vibration. There's no point trying to diagnose something when you have known components that could affect/contribute to the vibration.

You need to find out if the O3 seats have the same components, i.e. weight sensor. If so, you just need the wiring diagram to figure out the pins for each seat, then just splice in the connector from the 06 seats onto the 03 seats. If the components aren't the same, then I don't see how you would be able to make things work properly .

You can use the turbo legacy 18mm bar, or get the whiteline bar. I started with the turbo legacy bar and it was an improvement. As I started replacing other components in the suspension, I got the WL bar, which helped more.

This thread is done.....

They are different. The rear FWD bearings are ball bearings, while the rear AWD bearings are tapered roller bearings.

Did you check all your fuses, relays, & fusible links? If everything is good, you may have fried something. I scanned the electrical section from the 90 factory manual. It should be the same for the 91 http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/1990_Legacy_Wiring_Diagrams.zip

I'd try unplugging the O2 sensor and see how it runs. If you're not getting a code, chances are it's ok. You may need to swap the ECU. Was the 97 a MT as well? It could be a slew of things......never know what got tugged on during the swap, etc.

Pick up a used rear hub/ebrake at a junkyard. The parts should still be good. As for the parts being the same, yeah they should be the same. You could probably get a hub from a first gen legacy and they would work.

I'm not sure, but I don't see any reason why they'd be different.

It's probably the CV joints. Replace the axle with a reman'd one.

The sendor can be replaced separately of the pump. The senders run around $60 or so each, and there are two senders. If both senders weren't replaced, it's possible the other one is giving you problems. I ran into this with my 90 Legacy. Replaced one, still had issues, and then finally replaced the other to fix things.

Yes the newer subarus, legacies & Outbacks for sure do use CAN.

If they won't come out, you may have to take the changer out and get them out by taking the unit apart.

The sending unit itself is different as well. The FWD unit has a resistance of around 0-95 ohms, while the AWD units have a resistance of around 0-45 ohms each, which gives a combined resistance of around 0-95 ohms.

As Subaru said in their response, using lower octane fuels may cause poorer performance & mileage, and may cause knock under certain circumstances. Most fuels will meet and exceed their AKI rating, so if you're buying an 87 octane fuel, the chances are, it may be a few points above. The way the ECU's work, they will constantly monitor the engine knock sensors, and will push timing up until the point of knock. The chances are that if you drove around on premium for a while, and then had the car dyno'd the timing trims would probably be slightly higher. Also, in regards to resetting the ECU. The fuel & timing trims should be able to be erased by resetting the ECU, or pulling the battery.
