I have a code 34 on my buick regal. Where is the mass air flow sensor or intake flow sensor. The car will start fine drive for a while then die, and start right back up again then do the same thing again.

It's located either on your throttlebody or in your air intake before the throttlebody.

Hi,
Is your engine a 3.8 or 3.1. I have found out that the 3.8 does not have a MAF.

Actually, the 3800 DOES have a MAF (Mass Air Flow) sensor, but it doesn't have a MAP (Manifold Absolute Pressure) Sensor. The 3.1L only has a MAP Sensor.
