Your car’s engine can only run smoothly when it has the perfect air/fuel ratio. When there’s too much gas flowing into the engine, your vehicle runs rich, leaving tons of unburnt fuel behind. When that happens, you’ll notice many frustrating issues that impact your overall driving experience. Fortunately, you can count on our Mevert Automotive & Tire Center team to track down the cause and recommend just the proper repairs. Ready to get started? Here’s what you need to know.

Most Common Signs Your Car is Running Rich

When your car doesn’t burn all the fuel going into the engine, you’ll likely notice the following signs of a problem.

Strong Fuel Smell

The pungent smell of unburnt fuel is a surefire sign that your car is running rich. Your car should only emit a light exhaust smell when in the proper air/fuel ratio range. Anything more substantial than that, and you likely have a severe problem on your hands. Since this could signify that your car is leaking fuel, always get a tow into the shop when you notice a gas smell.

Check Engine Light

In modern cars, the onboard computer and its associated sensors constantly monitor the air/fuel ratio. When it goes too far outside the normal range, it will let you know by turning on the check engine light. So, when that light turns on, you know that it’s time for your Steelville IN auto tech to check for codes and see what’s going on.

Poor Engine Performance

When your car starts running rich, the incorrect air/fuel ratio often results in poor engine performance. You may notice that your car struggles to accelerate off the line and get up to speed promptly. Thankfully, your auto tech can restore the balance between spark, airflow, and fuel by finding the faulty parts and replacing them.

In addition to these signs, watch out for a marked decrease in gas mileage. If you find yourself at the gas station more often than usual, it’s a likely sign that your car is not running at its best. By coming in for auto repair in Steeleville, IL, at that time, you can likely save more money in the long run by simply getting the problem fixed.
