Dealer is replacing/splicing in a new harness/connectors for the air flow sensor...is this the MAF???
They are doing this in an attempt to stop the vehicle blowing excessive smoke ...head office has instructed them to do this even though the service department reckons the injectors are flogged and wants to replace them, this needs to be checked first apparently.
Anyone else had this done???......I thought a good squirt of cleaner would have solved this.
