1. Faulty spark plugs or ignition coils: If the spark plugs or ignition coils are not functioning properly, they can cause the engine to misfire, resulting in sputtering and a burning smell.
2. Fuel injector issues: A faulty fuel injector can cause the engine to run too lean or too rich, which can lead to sputtering and a burning smell.
3. Vacuum leaks: A vacuum leak can cause the engine to run rough and produce a burning smell.
4. Alternator problems: A malfunctioning alternator can cause the electrical system to malfunction, resulting in sputtering and a burning smell.
5. Overheating: If the engine is overheating, it can cause the electrical components to malfunction and produce a burning smell.
6. Electrical short circuit: A short circuit in the electrical system can cause wires to overheat and burn, producing a burning smell.
7. Catalytic converter issues: A clogged or damaged catalytic converter can cause the engine to run poorly and produce a burning smell.
It's important to have your car inspected by a qualified mechanic as soon as possible to identify the exact cause of the sputtering and burning smell and have it repaired.
