A chance the previous owner installed the wrong oil pressure sensor. One works with the light and the other with the gauge. They don't interchange.

It is a 3.70 if it came from an older Subaru. If from a newer Legacy, who knows?

I did the swap about 4 years ago. Recall the bulbs are different and can't be interchanged. Also I replaced the plugs but can't remember why. Maybe the original ones were melted. Still have the car, a 95 and I think the headlights came from a 98.

The knock sensor is sort of between the turbo and throttle body. Closer to the TB and easy to overlook. Screws into the block and only has one wire. vibration more than likely from a failing driveshaft.

Get some of this stuff. May take a week to dissolve the rust but it will given enough time. http://www.kanolabs.com/google/

That's it. Not worth it IMO replacing it. Just get another used alternator.

It's part of the alternator.

I'll add a few more tips. Loosen the camshaft sprocket bolts before removing the timing belts. The bolts you will be working with are small and easily broken. Go easy on them. Been my experience the 3 most important gaskets to replace to stop leaks are the oil pump gasket and the O-rings behind the camshaft sprocket housings.

Replacing the complete door/doors is the easy way. It is an unbelievable pita pulling and reinstalling the windows and all the associated hardware and then you have to do the adjusting. Been there and don't want to go there again. Windows also require a relay. Have no idea where it is located in a Legacy.

Seats will swap but will be much lower. May have a problem seeing over the dash. How are the front fenders on the XT? Know someone looking for some.

OP talking about the injectors. Almost sure they are fired in pairs.

Unless I tossed them, I should have a set of front calipers back in the corner of the garage. You can have them if willing to pay shipping. PM me if interested.

Where is all the air coming from to support idling at 7K rpms? I'd determine if the butterflys are open or still in a nearly closed position. If the butterflys are in a normal position, then major air leak downstream of the carbs. If butterglys wide open, then determine why.

Contact Edrach if you decide to just replace the pump. He has a good one.

May want to check the vacuum line to the modulator before swapping transmissions.

It is the rare 87.5 model and the transmission is the 4EAT. Will also have the spider intake manifold.

Someone here recently had the same problem. Turned out to be the igniter on the firewall.

My thinking is the engine has an air leak downstream of the AFM and as a result has low rpm power. Reason engine seems to run well in reverse probably due to torque multiplication: reverse gear geared lower than 1st gear.

Just replace it with one that is used but newer. . Thinking all models up to 2005 or thereabouts are plug and play. My 95 has a radio from a 2002 WRX.

Ball joints and tie rod ends are cheap so just replace them. Also check the bushings holding the steering rack.

Check the fuel pressure regulator. Pull the vacuum hose. If fuel drips out then replace the FPR. Can't believe all 4 injectors opened for some reason but i guess anything is possible.

If you really screw up the intake manifold, I have a spare one you can have for the cost of shipping.

PM me if interested in some new factory rear air struts.

No. My XT6 essentially has done the same thing for the last 11 years. Replaced the pump and the sender and that changed nothing. The HLAs have never developed the TOD so regardless of what the gauge shows, I know the engine has oil pressure.

This is a FWD model so no need to swap differentials. Also the FWD turbo transmission will have a 3.54 differential ratio. Not sure anymore about the axles but still think the turbo and NA axles are different.
