Posted to Ford Driveability on 1/27/2004 39 Replies

Last week we scanned and found 02 sensors stuck in lean position - replaced w/four oem 02 sensors - Two days later light comes back on with codes 171 and 174 lean condition. The 02 sensors (4) test ok. Had this problem with 98 windstar never resolved.
