Could getting bad gas when you fill up cause the check engine light to come on and lose acceleration?

Yes, getting bad gas when you fill up can cause the check engine light to come on and lose acceleration. Bad gas can contain impurities or contaminants that can damage your vehicle's fuel system and cause a variety of problems, including:

* Check engine light: The check engine light is a warning light that indicates that something is wrong with your vehicle's engine. If you get bad gas, it can cause the check engine light to come on because it can damage your vehicle's oxygen sensor or catalytic converter.

* Loss of acceleration: Bad gas can also cause your vehicle to lose acceleration because it can clog your fuel injectors or fuel filter. This can prevent your engine from getting the fuel it needs to run properly, which can lead to a loss of power and acceleration.

* Stalling: Bad gas can also cause your vehicle to stall because it can cause your engine to misfire. This can happen when the bad gas contains water or other contaminants that can cause the spark plugs to misfire.

* Engine damage: In severe cases, bad gas can also damage your vehicle's engine. This can happen if the bad gas contains harmful chemicals that can corrode your engine components.

If you think you may have gotten bad gas, it's important to stop driving your vehicle immediately and have it towed to a mechanic. The mechanic will be able to diagnose the problem and make the necessary repairs.
