If your Grand Am is exhibiting those symptoms (stalling, feeling like it's out of gas, and failing to restart), the TRAC OFF light is likely unrelated to the root cause. The problem is far more likely to be something affecting the fuel system, ignition system, or even the car's computer. Possibilities include:
* Fuel pump failure: This is a common cause of stalling and inability to restart.
* Fuel filter blockage: A clogged fuel filter can restrict fuel flow.
* Crank position sensor or camshaft position sensor failure: These sensors are crucial for the engine's timing and starting.
* Ignition coil or spark plug issues: Problems here prevent the engine from firing.
* Battery or alternator problems: A weak battery or failing alternator can prevent the engine from starting.
* Mass airflow sensor (MAF) issues: A faulty MAF sensor provides inaccurate information to the engine computer, causing poor running or stalling.
* Computer/ECM problem: A malfunctioning engine control module can lead to various problems.
While a consistently illuminated TRAC OFF light *could* indicate an underlying electrical problem that *might* indirectly affect other systems, it's highly unlikely to be the direct cause of stalling and starting issues. Have a qualified mechanic diagnose the stalling and starting problems; the TRAC OFF light should be investigated separately if it's always on.
