Did anyone check for codes causing the problem? Bad front O2 sensor caused CEL on my 99 9-5SE 2.3lpt for about 35,000 miles. The engine will still run good since it automatically goes to a rich mixture. Gas mileage suffers though. My gas mileage went from 22 to 24.5 mpg average when I had the O2 sensor and Turbo Bypass Valve replaced.
