3B poor running - pretty long

[alan cordeiro]

Your symptoms are very much like the symptoms I had with a completely DEAD
MAF sensor. Pull back the rubber boot over the MAP connector and measure
the voltage across pins one and five  while the ignition is ON but the
engine off.
It should be around 12 to 14 volts. if not check your wiring and fuses

If the power supply to the MAF is OK, make sure that you have around 2 volts
between
pins one and three. If so, then start the car and let it idle. Your voltage
should go up
by a volt or so. If no voltage under these conditions, your MAF is probably
dead.
