2.2 JTS Mass Airflow Sensor
Hi all - having a bit of trouble with this one and would appreciate your advice.
My 2.2 has a recurring temporary problem. Every few weeks it runs a little rough and slightly hesitant for a while until it has an 'episode'. It lurches, the engine seems to shut itself down slowly and progressively and a host of warning lights appear referring to failures of VDC, hillholder and others.
Each time it happens (bizarrely often after driving in heavy rain or going through a jetwash) the problem seems to diminish and after a few hours/days the engine warning light extinguishes.
The dealer says the system is logging an intermittant fault with the mass airflow sensor but as it is not a hard fault cannot rectify until the problem manifests itself permanently.
Could this also explain why the fuel consumption is so poor at the moment even considering winter driving (20 mpg around town on V-power)??
Anything else obvious that could be adrift??
Thanks for your thoughts.
