Mechanics

I HAVE A CHEVEROLET , AND IT STALLS WHENEVER IT FEELS LIKE IT. I BROUGHT IT TO A MECHANIC, AND TESTED IT, AND A MASS AIR SENSORY CODE CAME ON. SO I NEEDED A 2ND OPINION AND WENT TO ANOTHER MECHANIC, HE TESTED IT AND SAID IT WASN'T THE MASS AIR

2005 Chevrolet Epica • 81,000 miles

I took it to a mechanic, and used a hand held diagnostic scanner and came up with the mass air sensor code. I got a 2nd opinion from another mechanic, and he tested the mass air sensor, and said it was just fine, it wasn't the mass air sensor, he said it's the catalytic converter.

To rule out the catalytic converter -you have to check for an excessive backpressure-
