Engines Affected: 2.5L 4 Cylinder, 2.5L 4 Cylinder Turbo

Average Mileage: 66,367 mi (40,869 mi - 100,000 mi)

Sometimes the Check Engine Light illuminates because the computer detects misfires. Subaru released an improved spark plug wire set to solve the problem. The ignition coil should also be inspected for carbon tracks or short circuits between the contacts

Visitor, 2004 Subaru Forester, 2.5L 4 Cylinder Turbo, 90,350 mi

Engine started to stutter at idle last night. After 5 min, it was fine and running perfectly. Next day, ran perfectly for 15 min, then started to stutter when idling. Check engine light and cruise control light are on now. Never had a problem with this car before.

The check engine light illuminated and another dash light blinked continuously. I took it in to my mechanic, who said the wires and seals had to be replaced ($380). My friend had the same lights go off less than a week later and the Subaru dealer told her it was the catalytic converter.

Check engine light flashing, then going off. Eventually CEL stayed on. Diagnosed bad plug wires. They were just changed 1 year ago at 30,000 miles too. We'll see if thats the end of it.
