Mass Air Flow Sensor Problems of Buick Lacrosse

Traveling on interstate 57 during daytime hours. While cruising at 73 miles per hour in the right hand lane, the vehicle sputtered and lost all power. I coasted to a stop off the side of the road. I restarted the vehicle and everything seemed ok, so I continued on. A little later it sputtered again and started losing power. The power came back before it came to a complete stop. I called on star for a diagnostic check and they told me I had a fuel system problem and that if the car would run to continue that it was not a safety issue. They told me to take it to a dealer for repairs when I got home. I took the car worden-marten service center for repairs on March 23rd. To repair the car they: 1. Replaced cat converter and oxygen sensor 125cgmpp- $750. 47 a second incident occurred while traveling on interstate 57 during daytime hours. I was passing a semi tractor trailer with three cars following me while cruising at 73 miles per hour when the vehicle sputtered and lost all power putting me in a very dangerous situation. The vehicle coasted down to about 60 miles per hour before it kicked back in. I in the mean time had dropped back behind the semi with the three cars behind me and when I could I pulled back into the right hand lane. This was a very dangerous situation for me and my wife. I called on star for a diagnostic check and they told me that everything was ok. I took the car worden-marten service center for repairs again on April 19th to repair the car they: 1. Replaced mass -air flow unit and sensor $ 131. 39 who knows if it is fixed right this time? this was a very dangerous situation to be in for the car to fail.
