Re: Map or Maf ?
They are pretty reasy to identify.
The MAF sensor (assuming its in factory location) is attached to the airbox. Has a circle around it in the attached picture.
Yeah if the MAF is stuffed it will cause the car to run like a bucket o crud and use plenty of fuel. Not much can actually go wrong with the housing - more likely to be the electronics inside the sensor. It may be they're just dirty as drone said. Theres a couple of torx screws holding the electonics on the housing, be extremely careful with this bit - there's two wires on there, kinda like a filament in a light globe. Not hard to bust em.
So - if the engine looks like the atatched picture, it definately has a MAF sensor. Chances are the person just confused
