Why does your 1996 suburban shut off when you hit the gas pedal parked?

If your 1996 Suburban shuts off when you hit the gas pedal while parked, it could be due to a few issues. One possibility is a malfunctioning throttle position sensor (TPS) that incorrectly signals the engine control unit, causing the engine to stall. Another potential cause could be a vacuum leak or a fuel delivery issue, such as a clogged fuel filter or failing fuel pump, which disrupts the air-fuel mixture needed for smooth operation. Lastly, it's worth checking for any engine codes that might indicate specific problems.
