Hi all Got the above vehicle in at the mo, it has a intermittent misfire at idle and on the road under load the misfire is there all the time. Checked the air mass that seems fine also looked at the injector quantity deviations there as follows.
-0.66 mg/str Injection Quantity Deviation Cyl. 1 0.14 mg/str Injection Quantity Deviation Cyl. 2 -0.59 mg/str Injection Quantity Deviation Cyl. 3 1.08 mg/str Injection Quantity Deviation Cyl. 4 0.0 Injector Status Cylinder 1 0.0 Injector Status Cylinder 2 0.0 Injector Status Cylinder 3 0.0 Injector Status Cylinder 4 -74.0 Switch Time Deviat. Cylinder 1 -40.0 Switch Time Deviat. Cylinder 2 -58.0 Switch Time Deviat. Cylinder 3 -46.0 Switch Time Deviat. Cylinder 4 Saturday,08,August,2009,14:25:57:55738 VCDS Version: Release 805.4 Data version: 20090602
These readings were taken at idle i dont have any readings from the road. Cylinder 4 looks as though the reading is too high, i thought that the readings should be near zero or in the minus. Any advice would be most appreciated TIA.
