Take the negative battery cable off for one minute.

Here is how to retrieve codes on the Subaru: http://www.2carpros.com/articles/subaru-diagnostic-trouble-code-definitions-1987-1994-obd1-with-code-gathering

Hi could be a whole list of things. If the car has been rebuilt and runs good its most likely just a minor prob best bet it to get it tested and an auto electrician, it will only take a short time and the scan tool will get the exact code to identify the prob.

Have you replaced the timing belts recently? The timing belts in these cars run both the cams and the distributor. If one comes off or breaks the engine wont do anything. The fix is not too bad if it is just the belt(s)

I am not 100% sure but you may have a bad cam or crank sensor.
Now whether this car has those parts or not, you can find out from your local parts distributor or you can go online. Do you have a check engine light on?Good Luck Friend.

have vehicle scanned for codes auto stores such as auto zone /advanced auto do it for free this gives u a starting point as for ur question about 25 different sensors there are about 60+ different codes and anything from bumper to bumper can set off check engine

It may be a plugged Cat Converter. They usually plug up at about that many miles. The check engine light will come on when that happens.
Try going to a auto parts store. They usually have a code checker to discover the problem in order to sell the parts to fix it. Try that first.

the only way to get the water out isto drill a hole in the bottom of the headlight assemly. they don't come apart. drill very slowly.

hope this helps
please rate well.

Yeks, quick (when engine cool) make sure your radiator is FULL and engine is AIR BLED at the thermastadt. If your master brake cylinder is assisted power your DIAPHARM could be ruptured. Causes low vac in system so heater controls only work at idle the changes to cold when driving

mil is the malfunstion indicator lamp (check engine light) there is a connector either under the dash or under the hood near firewall that is normally not plugged in to anything. Use a paperclip to jumper this and the engine light will flash codes. i think the connector is green but check a repair manual to be sure. there are other connectors that you don't want to mess with by accident
