I have a 1997 Subaru Legacy Outback AWD. The check Engine light is on and is coming back as a cylinder 1 misfire. I've replaced the wires, plugs, coil & even the injector. Compression is still low. The only difference I see is when I'm at a standstill. When there is a load on the car it runs great. Any ideas on how to do a quick fix on this problem?
When you replaced the plugs , was one of them (cylinder 1 ) dirty and fouled ?
I'm thinking that bad rings in cylinder would give you low compression , and eventualy cause the missfire by fouling up the plug.
There is an inexpensive product that will help with the compression by filling up scratches in the cylinder walls. It is called Restore , and it is one of the only products of its type that I have used , and feel actually works.
Unfortunately , if your rings are broken , or badly worn , nothing in a bottle will fix them.
If your car had a distributor cap and rotor , I would change them too.
If you have low compression in one cylinder it could either be bad rings (which is unlikely) or a burnt valve. Solution is to remove head and have valve replaced.

It does have low compression...25 lbs. Where do you pick up Restore?
