2006 Subaru Impreza WRX STI Problems

Improved Spark Plug Wires for Misfire Issues

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.

Check Engine Light Due to Failed Knock Sensor

The Check Engine Light may illuminate because of a failed knock sensor. Although the sensor often tests okay, it can fail intermittently, while the vehicle is being driven.
