Can bad gas cause your car to misfire?

Yes, bad gas can cause your car to misfire. If the gas contains impurities, such as water or dirt, it can clog the fuel injectors and prevent them from delivering the correct amount of fuel to the engine. This can cause the engine to run lean, which can lead to misfiring. In addition, bad gas can also damage the catalytic converter, which can further worsen the misfire. If you suspect that your car is misfiring due to bad gas, you should have the fuel system inspected and flushed.
