What causes a backfire through the intake valve?
The manifold’s job is to provide a mixture of air and fuel to the engine’s cylinders. To do this, the intake valve opens to draw gas and air into the engine. After opening, the valve closes to keep this air and fuel combination trapped inside. Backfiring is a small explosion.

Valve issues may also involve poor fuel economy, rough idle, stalling, high oil consumption, hard starting, and exhaust smoke. Valve problems of these type tend to create a more consistent backfire condition. You may diagnose valve problems at home with the use of a compression gauge or a vacuum gauge.
