My LaSabre has been running badly in the cool mornings. If you step on the
gas it coughs and sort of back fires. It has new plugs and wires. At high
speeds the check engine light comes on and if you try to speed up it
hesitates. I took it to Auto Zone and it came up with a code 44 but I don't
think the IDIOT that did it had a cute of what he was doing I plan I taking
The code was O2 sensor and something about Mass Air Detector. I am leaning
toward the Mass Air.
What do you of great knowledge think/
