Exactly this. Even if the mass air sensor fails, the ECU (brain of the car) reverts back to a factory default RICH fuel map.

Lean mixtures backfire from incorrect timing.

Timing sensor (crank and/or cam) fails in a modern car, it stops running immediately. Crank all you want, it will not backfire, let alone start.

The crooked in this matter, need to update their excuses, they are pure 1970's garbage.
