The #1 cylinder. The front passenger side.

If you are checking resistance where the spark plug wires connect the resistance should be between 17.9K to 24.5K

if memory serves its the shift lock button,it allows you to move the stick when engine is off and in park.so you can tow the car the max 35 miles @ 30mph to a local garage.

there not a certain type for that car really. You can use any kind sold at your local gas station.

You need to have the computer scanned to see why the check engine light is on. Once you have the trouble code(s) you can than start researching ways to resolve them.

The check engine light comes on because it sees a fault with either a computer controlled device, and input sensor, or a monitored system. It has nothing to do with the oil or filters. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

some of the problems that makes the engine shake are...
spark plugs,engine mount,or one or more cylinders are not functioning.
lets just hope its a spark plug...
usually if you clean your engine...some water gets to the spark plug and then the engine starts shaking...so check if the spark plugs are filled with oil or water...or anything else...or it might just be that it got warned out...good luck!

the problem may be in the mas. Mas Airflow Sensor. Locate on the air filter or in the line between the throttle body. Usually when these go out the car won't rev up very quick. if you slowly press on the gas pedal the rpm's will climb a little at a time. Hope this is helpful.

try to jump start your car see if the interior lights are real dim headligjhts maybe you drained your battery too much or burned your alternator also check the fuse for your alternator see if blew hope this helps also check the fuse for your battery and check make sure the terminals are tight not dirty

termostat is on the engine block
on the bottom rad hose. yes under the engine on the right side of the car when
facing from the front to the rear.
youre welcome marc godin.

Take it to midas

either an ignition module or a sensor on a vehicle this old ,think the sensor might be inside the distributor on this one,and the module under the coil

yes but if he rebuilt it you should have some kind of warrenty with this guy If you dont get satfation go to small clain court the overdrive is part of ths Transmission.

I haven't been able to find schematics free online.Some local libraries carry haynes or chilton repair manuals to look at.You could go to a national auto parts store and "thumb through" one(bring pen and paper).If all those lights are controlled by a column that sticks out from the steering wheel,I would say you probably need to take apart the steering column a little,and maybe try buying a used stick from a salvage yard if one is nearby.Let me know what you find out please. Good luck! Greg

He is not cleaning the pan and attaching surface....Should also use adhesive........Hope this helps.

Could be a Bad VSS ( Vehicle Speed Sensor ) or an Electrical Problem for your Speedometer ! For Check Engine maybe a coincidence or a code telling a Sensor is Bad.. ! Most of the Subarau I saw from the year has a Check Engine with one or many code.. several time it's a Pcm Problem.. because all the code tell's you at the end if everything if fine : Change PCM.. so first i Would check your Vehicle Speed Sensor ! And Check the Code from the Check Engine !

If the check engine light goes on for any length of time, there probably are codes stored in the computer that can give you clues as to what is wrong with the electronic engine controls, or mechanical parts on the engine.
Reading Codes 1985–94 vehicles Codes are displayed by the MIL flashing ON and OFF. The time duration of the flash identifies the significance of the digit. Three flash durations are used:

• A flash duration of 0.5 seconds indicates no malfunction (OK).
• A flash duration of 1.3 seconds indicates that it is a 10's digit.
• A flash duration of 0.2 seconds indicates that it is a 1's digit.

For example, if 3 flashes — 1.3 seconds long — are followed by 4 flashes — 0.2 seconds long — a Code 34 is indicated. These code sequences are separated by 1.8 seconds to avoid confusing tens and ones digits.

• Read Memory Mode: used to pull codes which have been stored in memory. It is most effective in detecting poor contact of wiring harness connectors. To enter this mode, connect the read memory connector with the ignition ON.
• D Mode: used to diagnose and test the entire injection system. To enter this mode connect the test mode connector with the ignition ON. On the Legacy and SVX, the ignition must be ON with the engine running.
• F-Check Mode: used to measure the performance characteristics of the injection system components. When working in this mode, a Select Monitor or equivalent scan tool is required.
• U Check Mode: operates during normal engine operation. It signals the driver using the MIL only when components necessary for start-up and drive are faulty. The read memory and test connectors must be disconnected with the ignition ON for this mode to be operational.

Clearing Codes 1985–94 vehicles With the ignition ON and the engine running, connect both the read memory terminal and the test mode terminal

either a o2 lambda sensor or air pressure valve has gone
simple fix

yes they have a timing belt and should be changed every 60k. now honestly everyone is different but ill tell ya what subaru are the easiest and simplist to work on almost nothing to them and they run forever.but that is my opinion.ah prices all pending where you live but i wouldn't charge more then $300-350 to change one.it is about 3 hours to change for sohc and 4 for dohc estimate about $80-100 for most shops now a days.The belt runs about $50-60 bucks but sometimes pending mileage i would change out the belt tensioner they run about 100 buck so be prepared. but youll prolly never have to change it again though.like i said they last for ever!!!
