Unusual Exhaust SmellĪ bad fuel injector can cause an unusual smell from your exhaust, as excess fuel or unburned fuel may be released through the exhaust system. This can result in sluggish performance and a lack of responsiveness when pressing the accelerator. Your Chevy Tahoe may experience poor acceleration if the fuel injectors are not providing the proper amount of fuel for combustion. In severe cases, this can prevent your engine from running altogether, leaving you stranded. 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.

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 Tahoe’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 Tahoe 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 Chevy Tahoe has bad fuel injectors, you may notice a rough idle.

The first is for them to become clogged, dirty, or unresponsive.There are two main ways that your injectors can fail to do their job properly. 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.
