Will a malfunctioning tps cause the engine to stall at the same rpms every time or would it fluctuate?

A malfunctioning throttle position sensor (TPS) can cause the engine to stall, but the stalling may not occur at the same RPM every time. Depending on the nature of the TPS fault, the stalling can be triggered at different RPMs due to variations in throttle input, engine load, and other factors. Fluctuations in stalling behavior can also arise from related issues in the fuel or ignition systems.
