have a 95 850 turbo wagon and the check engine light has been on for some time. Want to sell and don't want CEL on when I sell it. Runs real nice. Checked codes as per this site and none registered. Took it to local mechanic and he hooked OBDII and checked codes and none there either. No engine codes faults but have a red flag in the Parameter ID section of print out stating "long term fuel trim - bank 1 -10.16%".

Statement at bottom of print out states -

"Currently, one or more Fuel Trim Values indicate the Engine Management System is making a substantial adjustment to fuel delivery.Further investigation required.

Would love some advice or suggestions.
