Your fuel injectors are what get fuel into the combustion chamber; the cylinders to be exact. If your automobile has direct fuel injection, the injectors spray the correct amount of gasoline into the cylinders. If it doesn’t have direct fuel injection, the injectors spray the fuel into an intake manifold. Either way, CAR FIX Cookeville warns that if your fuel injectors are clogged, your engine performance will suffer. Here are the signs of clogged fuel injectors.
Misfiring Engine
Alongside fuel, the cylinders also have air pumped into them and this mixture is detonated by the spark plugs. This creates the combustion your engine needs to start and keep running until you turn it off. If there isn’t enough fuel in the cylinders, the engine will misfire or feel as if it is sputtering. This is because the air and fuel combination is air-heavy or lean, and your engine is being starved of fuel.
Rough Idling
You will also notice problems with your vehicle’s idling. The engine will sputter while you are sitting at an idle, too. If the fuel injectors are really clogged, your engine might stall. You might also notice your RPMs are sporadic when you glance at your tachometer. The needle will dance about as your vehicle struggles to keep running and not stall. This can also happen while your automobile is in motion.
Reduced Gas Mileage
Another sign of clogged fuel injectors, or leaking fuel injectors for that matter, is a reduction in your vehicle’s fuel economy. The engine has to work harder if the air and fuel mixture is off-balance. This will cause the engine to burn more fuel, even though it isn’t getting enough through the clogged injectors. If the fuel injectors are leaking, your gas mileage will also drop and you’ll need to fill up more often.
Dead Engine
Finally, if the fuel injectors are clogged to the point that no fuel is making it through to the cylinders or intake manifold, you won’t be able to start your automobile. You might also stall and then be unable to get your car, truck, crossover, or SUV started again. A professional cleaning is in order to restore your engine’s performance if the fuel injectors are clogged so much that the engine is dead.
