had the car hooked up to diagnostics machine at a mates garage, (intermittent slugish drive). It didn't show any faults or problems. Had a new EGR Valve fitted last week, car drove ok for 2 days , then sluggish again, not codes. checked all hoses all ok.

The guy showed me that the "Mass Air Flow Sensor" reading on the machine shows that their is no "Voltage" being sent from the MAF. The MAF g/s bit shows the reading but the MAF voltage bit is showing 0.00.

Does this mean the MAF Sensor is KA'PUTT? Any ideas?
(The injector leads and connectors all look ok)
