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

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.
There is a technical service bulletin on the ABS control module. It is replaceable without having to replace the entire anti-lock brake hydraulic unit. Previously, the ABS control module was only available as a complete assembly that included the hydraulic unit.

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.
