Another MAF fault question (GTV V6)
I need some advice please.
I have a 1999 GTV 3.0 V6.
When idling, the engine speed is slightly irratic (hunting). The revs will drop until it almost seems like it will stall, and then they will pick up slightly. Also when hot, sometimes the engine will cut out when setting off from lights etc, left for a few minutes it will then run ok.
I have alfa diag, and fault code P0100 is shown;
Failed Component Code: Air Flow Meter
Fault Symptom: Below Minimum Limit
Warning Lamp Status: Warning Lamp Illuminated
Fault Test State: Test complete for this Error or not applicable.
Fault Code Storage State: Error Present at time of request
Event Count: 64 count
Filter Count: 0 count
However, when I monitor the air flow meter in the sensors tab of alfa diag, it seems to be recording a temperature and flow.
The idle speed according to alfa diag is around 600-650rpm which seems a little low to me?
I've tried cleaning the MAF and the connector, but no change. Also with MAF disconnected the engine idling is the same.
Any advice on whether this is the MAF, or maybe something else causing the MAF fault would be appreciated, before I splash out on a new one.
