STILL having problems with car - when warmed up starts to misfire
2001 AUM 1.8T - Remapped
Here is a list of parts changed
4 Coil Packs on recall
4 Spark Plugs
FULL Coil Wiring Harness
MAF Sensor
N249 Deleted
(and yes i have swapped coils packs and mis fire doesnt follow the coil pack when swapped around)
And here is the lists of codes i keep getting after deleting codes twice over -
17608 - Boost Pressure Control Valve
16684 - Misfire Detected
16687 - Cylinder 3 Misfire
16384 - ??????
16486 - Mass Air Flow Sensor Low Voltage
Anybody any ideas as i am struggling could it be a faulty MAF/MAF wiring i have disconnected the MAF (but not sure how long it has to be disconnected for to notice a difference)
HELP PLEASE :cry:
-
leave it disconnected maybe? then see if it still misfires?
-
you tried a new temp sensor on it :smiley:
-
Left it disconnected for about 30 secs still was same thats why i said how long would need disconnect for?
Not tried new temp sensor wouldnt that mean that the fans wouldnt kick in though if that was faulty
-
Fans will still work if temp sensor fails
-
Oh right anyone think this could be the cause or are they expensive and also where abouts are htey on the car?
An error code hasn't come up thogh?

check the injector loom, and swap the injectors around to see if the misfire moves with it. if its still misfiring on cylinder 3 then its time for a compression test. if compression comes back good put the engine to TDC and see if pistons 1 and 3 are sitting at the same height. a slightly bent rod can cause these symptoms :undecided:
