Why would a 2002 Mazda Tribute Engine sputtering when started but stops after running for awhile?

A 2002 Mazda Tribute engine sputtering at startup but smoothing out after running for a while could indicate several issues, such as a faulty fuel injector, clogged fuel filter, or spark plug problems. At startup, the engine may not be receiving the proper fuel-air mixture, leading to sputtering. As the engine warms up, it may compensate for these issues, allowing it to run more smoothly. Additionally, issues with sensors like the mass airflow sensor (MAF) or throttle position sensor (TPS) could also contribute to this behavior.
