2002 Ford Explorer XLS 4.0L Low Power at Times
Posted to Ford Driveability on 3/8/2011 17 Replies

I have replaced all of the oxygen sensors for these codes, and the light stayed off for about 3 weeks, now back on with same 2 codes. O2 sensor have been replaced twice so far, so I don't think it is that. Any other concerns that pop up causing these codes?
