How much the ecu is having to compensate for correct fueling
+/-10% is within tolerance. Anything higher indicates you have a
problem. First column shows the compensation @ idle. The second shows the compensation @ part throttle.
- numbers would indicate the car is possibly running rich and having to remove fueling.
+ numbers would indicate the car is possibly running lean and having to add fuel. (+ in the first column would indicate a vac leak, + in the second would indicate possible problems higher up the revs... maybe maf)
Best to reset/clear codes to reset 032, then drive around normally for a hour or two. Then check again.
