Problems with the mass airflow (MAF) sensor can actually cause the main computer chip to turn on the check engine light. The most common issue an MAF sensor faces is getting too dirty. When this happens, the sensor may start to malfunction and create a ton of engine problems. Guaranteed Auto Air & Repair is going to list those problems below.
Acceleration Trouble
A malfunctioning MAF sensor can convince the main computer chip that the cylinders need more air when they actually do not. Unfortunately, the extra air in each cylinder will create problems with your vehicle’s acceleration. The extra air produces a lean fuel mixture.
Idling That Is Rough
This lean fuel mixture is also going to create problems when your engine idles. While you are sitting at a red light or stop sign, you will feel that the engine is idling roughly. In severe cases, your engine may actually stall because it cannot continue to produce combustion.
Surging or Hesitation
Another engine problem that occurs with a dirty MAF sensor is hesitation while you are driving. This, too, is a sign that you are dealing with a lean fuel mixture in the engine. Your car’s engine may also surge if the main computer chip thinks the engine needs more fuel.
Reduced Gas Mileage
To rub salt in the wound, figuratively, when your engine is struggling to perform or surging, it will use more gasoline or diesel fuel than it normally does. Consequently, you will see a reduction in your gas mileage, and this is due to the malfunctioning MAF sensor.
Black Engine Exhaust
We wish we could say that this is the only problem you will have with your automobile, but it isn’t. In addition to surging, the engine will also produce black exhaust when it uses extra fuel in the cylinders. Consequently, you will see black exhaust behind your automobile.
Hard Starts or No Starts
Finally, if the MAF sensor is in really bad shape, it can actually affect your ability to start your automobile. You may find it hard to get the engine to fire up, or you may be unable to get the engine to fire up. Either way, this problem is extremely frustrating.
