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

Subaru Impreza WRX Problems
Check Engine Light Due to Failed Knock Sensor
Engine --
Verified
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.
Improved clutch parts to correct clutch chatter
Drive Train --
Verified
There have been reports of "clutch chatter," particularly when driving the vehicle from a cold start. If the issue was reported by the owner while the vehicle was still under warranty, the dealer may replace the clutch with improved parts.
Air Pump Valve
Exhaust & Emissions --
michaelshibley
The air pump rusts out causing the the valves to get stuck open or closed. This appears to happen more frequently around wet areas (snow or humid). There are two valves; for the first one all you need to remove is the inter-cooler, the second valve is between the intake manifold and engine block.

Subaru Impreza WRX Reviews
We bought this used in 2004 with 24K miles. Now at 220,000 miles and still going strong. It is a joy to drive.
I love this car, the only thing is, the motor was rebuilt prior to me purchasing the car.... After the rebuild the car drove amazing, after replacing a hose that goes to the turbo that was broken causing an intake leak. Later, i noticed my car was going through gas like i have never seen, i ran OBD2 Diag. on it.... Short term fuel trim is at -25 at idle!! and also while driving. I did some research and was looking at Blow Off Valves... noticed that the stock was a recirculating BOV. I disconnected the hose that ran from the BOV to the intake system so i could get the "pshhh"... could that be what is causing my fuel problem?? Should i re-connect that hose? Or are theyre any other ideas on what i should do. I cannot drive the car until it is fixed because the gas mileage is so terrible.
Only had this car 7 months and is my daily driver. Perfect blend of performance and practicality with good safety ratings too.
Only thing that I feel cheated on are the brakes. I mean everyone else has nice big 4 pot, 2 pot brakes, and we are the ones who have to upgrade and spend that much more on brake set ups and the money on them. :( kinda sad , but I have 2 Bug-eyes and love them both!
purchased second hand in 2006. Still going strong in 2010. Basically only regular maintenance needed. Very reliable.
