johnceggleston Posted January 14, 2012 Share Posted January 14, 2012 change the wires first. use subaru or very high quality wires. cheap wires can cause issues right out of the box. wires are easier and are likely to correct the problem. or to test if it is the wires, move the #3 wire to a different cylinder and drive it for a while. changing the plugs is a little challenging because the spark plug tubes are level with the frame rails of the car. and there isn't a lot of working room.

davebugs Posted January 14, 2012 Share Posted January 14, 2012 A 1" extension and a swivel spark plug socket. Also I prefer a real long extension often. Sometimes it's easier to actually have the ratchet out of the engine bay with like a 2 foot extension ratehr than finding room to turn it in the close quarters. Removal of air box, washer tank highly recommended. Don't forget anti-seize and dielectric grease. Link to comment Share on other sites More sharing options...
AKwhitetrash907 Posted January 14, 2012 Author Share Posted January 14, 2012 it was the plugs. i put a can of sea foam in the tank a few days ago and am assuming the excess carbon residue formed on the end of the number 3 plug. it was caked. i will take a pic tomorrow and post it up. i used a 3/8" drive spark plug socket with a 1 1/2" swivel and a 1" extension on that. removed the air box, washer fluid bottle and the battery and tray was a bit of a pain in the butt. i got it done in an hour and a half.9(probably would have taken less time but i was wearing gloves and shivering profusly) never had such a battle to change 4 plugs in my life. runs great now.

Glad to hear your success in changing your plugs. I have done that same work on my 99 OBW, so I know how awful changing 4 spark plugs can be. It has to be one of the worst jobs, when working on a Subie. I know your pain. Again, congrats on successfully changing the plugs. Link to comment Share on other sites More sharing options...
