Your GMC truck may be backfiring due to several issues, such as a faulty ignition system, incorrect timing, or a rich air-fuel mixture. Other potential causes include a malfunctioning fuel injector or exhaust leaks. It's important to diagnose the problem accurately, as backfiring can lead to further engine damage if not addressed. Consulting a mechanic for a thorough inspection is recommended.
