Engine StallingĪ faulty fuel injector can cause your engine to stall, particularly when idling. This can make it more challenging to start your vehicle, especially if the problem persists. If your fuel injectors are clogged or damaged, they may not provide the necessary fuel to start your vehicle’s engine. But, you’ll definitely notice the lack of power. Typically, as the engine RPM increases, you won’t be able to “feel” the engine misfire as much. This can lead to a loss in power and acceleration, making it difficult for your vehicle to perform at its best. Misfires and Loss of Powerīad fuel injectors can cause misfires in your engine due to an incorrect air-fuel ratio. When one or more of the fuel injectors aren’t functioning properly, the ratio will be off and fuel mileage suffers. Your Encore’s PCM is constantly adjusting the air/fuel ratio and timing to get optimal combustion. It may feel like the engine is about to die as the PCM (powertrain control module) struggles to maintain idle speed. That is to say there will be a sudden drop in idle speed. It’ll feel almost exactly the same as if it had a bad spark plug. With a fuel injector that is not properly atomizing fuel properly, your Encore is going to have a difficult time idling.
This occurs because the injectors are not providing a consistent flow of fuel, causing the engine to operate unevenly. When your Buick Encore has bad fuel injectors, you may notice a rough idle. In some cases, you may notice a bad fuel odor at idle or experience engine stalling.ĭetecting these symptoms early and addressing the issue can prevent further damage to your engine and keep your Encore running smoothly. When a fuel injector isn’t functioning properly, it can cause problems such as misfiring cylinders, the check engine light, or even a vibrating engine. When they leak, they can really cause some issues
There’s always more than one fuel injector, and even one going bad is enough to make a noticeable impact on the drivability of your vehicle. That being said, bad fuel injectors are one of the more common issues that happen to any vehicle (Buick Encore included). Fuel injectors can go the life of a modern vehicle with little to no trouble at all.
