Yes. A sticking fuel injector can allow far too much fuel into a cylinder.
When you drive with a bad fuel injector, your engine will often misfire. You might also have a rough idle and increased fuel consumption.
Excessive fuel consumption in a Cadillac can be caused by several factors, including engine issues like a malfunctioning fuel injector, a clogged air filter, or a failing oxygen sensor. Poor maintenance, such as infrequent oil changes or neglected tire pressure, can also contribute to decreased fuel efficiency. Additionally, driving habits, such as aggressive acceleration and excessive idling, may further exacerbate fuel consumption. Lastly, the vehicle's weight and aerodynamics can play a role in how efficiently it uses fuel.
A bad fuel injector can cause an engine to continue running, for a few seconds, after the engine to shut off. The engine continues to run because of excessive fuel in a piston.
