Dear All,
2000 Lanos with high fuel consumption.
Managed to get it scanned.
At idle these were the readings.
Kindly help interpret them.
1.Fuel System.....CL
2.Load..............3.9
3.ETC................87 - 91
4.MAP................40
5.Spark Adv.........4
6.IAT.................40
7. O2.................410 - 810
8. O2 (second one) 190 - 220
9. TPS.................0
Will any of these values cause excessive fuel consumption( 150 miles to a full tank of 10 gallons)
Thank you

If the [#7 O²]values ​​are in mV the (410) lowest is too high. It should be less than 200. Does it goes down if you squeeze the vacuum rubber tube of the pressure regulator?
