Hi All. Have this car to see on Monday (again) and on 1st visit 2 weeks ago the EML was showing PO170 - fuel trim. Emissions were all good and no faults found. Car drives well with no problems. Took light out and now it is back on. Vehicle is low mileage about 9000 miles and owned by a pensioner who doddles about in it. Memory thinks high positive fuel trim at about 25 which I take to be running lean. May be wrong on that but will check detail on Monday. Now here's the thing. I can remember seeing 3 of these in the past year with exactly the same code but no running problems. On each occaison, the pre cat 02 sensor was changed as a start and as I heard nothing more,assumed problem was solved. This gentleman is an old customer of mine and as a pensioner does not have money to spend on "possible" fixes. Would be grateful for any inputs to solve this problem. Regards Pete M
