Fuel injectors replaced the carburetor years ago. Whether you drive an automobile with direct fuel injection or fuel injection into an intake manifold, your vehicle will not run well if the fuel injectors are clogged or leaking. The fuel injectors spray the gasoline into the combustion chamber so your engine can generate combustion. Ultimate Auto Repair lists the signs that your fuel injectors are having problems below.
Hard Starts
If the fuel injectors are clogged or dirty, you are not getting enough fuel into the combustion chamber and you may have difficulty starting your car, truck, or utility vehicle. Depending on how severely the injectors are clogged, you may not be able to get your vehicle started at all or it may take several cranks.
Rough Idling
Once you get the vehicle started, if it still isn’t getting enough fuel, your engine idle will be very rough. You will not only hear the engine struggling to run but you will also feel it. Rough idling is definitely a sign that you have dirty fuel injectors that are likely clogged by carbon deposits.
Excess Emissions
If the fuel injectors are leaking, the excess fuel will make its way into the combustion chamber and be burned away. This introduces excess carbon into your vehicle’s emissions and you will fail any emissions test that you take.
Poor Engine Performance
Another sign that you have clogged, dirty, or leaking fuel injectors is engine performance problems. If the injectors are dirty and clogged, your engine will stutter and struggle to run. If the injectors are leaking, the engine will surge forward and buck like a bronco.
RPM Problems
You may also notice that your RPMs are revving high or revving sporadically because the engine is not getting an even distribution of fuel infusion into the combustion chamber. This can be caused by clogged fuel injectors where the fuel makes its way into the chamber in spurts. This can also be caused by leaking fuel injectors. In this case, your RPMs will rev high as the combustion chamber burns away the excess fuel.
Poor Fuel Mileage
Finally, if the fuel injectors are not sending the fuel into the chamber as they should be, your engine performance and efficiency will suffer and, as such, your fuel mileage will suffer. It is impossible for an engine to give you the maximum amount of fuel economy if it is not running efficiently.
