Your Fuel A near-empty fuel tank does not have the energy to accelerate your vehicle.

The mass airflow sensor measures the air entering the engine and the engine control unit is then calculating how much fuel should be injected into the engine. Why does my car roll up an incline while in drive without touching the gas. Bad gas could be full of dirt and debris that is clogging up your lines and filters.

However there is no such feature on a automatic transmission. Manual cars and some automatic gearboxes shifting robots disengage the clutch when standing still. That is because of the torque converter.

This could be a known problem by the manufacturer so you may want to contact the dealer to see if this is anything that is covered.

Yes if the road slopes upwards or you encounter headwinds there will be greater loads to overcome without necessarily going faster which involves acceleration. If it fails your car will likely not be able to accelerate at all and may even stall out.

The catalytic converters job is to convert harmful emissions from the engine into less harmful emissions. The mass airflow sensor also known as the MAF sensor is connected to the air cleaner. The car may not be getting the right mix of air and fuel to burn the spark plug may not ignite at the right time the exhaust gases may not be leaving the system correctly.

Clogged Mass Airflow Sensor. Commonly this sensor gets dirt if you have an open-air filter or havent changed the air filter in a while.
