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

    My check engine light will blink and then go off and then a few days later it will be stay illuminated. I have checked the problem with the code reader and its says misfire and it always gives a different spar plug #. I just had these replaced less than 6 months ago there should not be any issues!!
