I just got my first Subaru from my sister in law for free.

It is a 93 Loyale 4dr front wheel drive with 3 speed auto, 154k.

The oil pressure light is not on and the wire is just hanging from the

front of the motor not hooked up. How are the idiot lights wired in

these cars I figured the light should be on constantly.

The bulb has been checked and is good.

Also it is real underpowerd in second gear mid rpm, Is there a

problem with the cats plugging up?

Any help will be appreciated.

Thanks

I'm pretty sure the sender for the oil light only makes signal when the pressure is too low. It not being hooked up will never give a signal for the light to come on.

Umm.. its an AT..the fix would be a 5 spd swap ;) :grin: ...seriously..the ATs are known for being very underpowered.

First and formost welcome to the good ship USMB

I just got my first Subaru from my sister in law for free.

Free is a good price to pay.

It is a 93 Loyale 4dr front wheel drive with 3 speed auto, 154k.
She's a pup, you have an EA82 engine with SPFI
(Single Point Fuel Injection also known as throttle body injection)

The oil pressure light is not on and the wire is just hanging from the
front of the motor not hooked up.

Look down the front of the engine or look up from down under,
you will see the oil filter, on the assmembly the oil filter
screws onto will be the oil pressure switch.
Probably has a wire and connector or just a slip on type spade connector.


How are the idiot lights wired in
these cars I figured the light should be on constantly.

The light gets battery voltage to one side from the ignition switch.
The oil pressure switch (a normaly closed pressure switch)
provides a ground for the lamp when the oil pressure is near zero PSI.
It should be on any time the key is on and the engine is not running.
This is an "idiot light", if it comes on while the car is in motion you are in trouble,
many folk fit an aux. gauge
using the pressure switch hole for the gauge adapter


Also it is real underpowerd in second gear mid rpm, Is there a problem with the cats plugging up?
With the miles you have it is unlikely but a possibility.
They are underpowered when coupled with the "3AT" auto tranny.
Try a can of Seafoam in the gas tank
and give it a tune up of plugs and filters. You may be due for a timing belt.

Any help will be appreciated.
Thanks


You are most welcome hope this helps some.

I didnt notice it was an AT. Your problem is VERY VERY common, and as bucky said, the only fix is a fivespeed swap or alternately, installing an EJ22 engine for more power.

Every one of us that gets the AT eventually asks the same question. The only answer I have found is to keep the pedal floored all the way thru first, and until you reach your desired speed. Fuel economy might suffer.. (I don't KNOW because I can't keep my foot totally out of it for a whole tank. traffic down here is awful if you don't have the pep to get around them all.) but really the car isnt that slow.
