Is Your Lexus Engine Sputtering

If you have a problem with your Lexus engine sputtering, it's likely something you'll notice right away. It may seem, at normal power, your engine simply isn't working right, or you may notice that it's backfiring. What's the problem? Fuel combustion is not being achieved in a sputtering engine. It could be something serious or a very simple problem. It may have to do with the exhaust system, fuel system, the engine, and more.

Here, we'll examine some of the most common reasons that engines sputter.

Faulty Gaskets or Seals

Throughout your vehicle's engine, cooling system, transmission, exhaust system, and fuel system, there are various gaskets and seals. If one becomes weak or worn, performance problems can result.

MAF Sensor Failure

In today's vehicles, an MAF (mass air flow) sensor is present. It controls and monitors the mix between air and fuel in your engine. If one of these sensors is faulty, a sputtering engine could be the result.

Oxygen Sensor Failure

In your vehicle's exhaust system, oxygen sensors are important. If, to the car's computer, false readings are given – or if an exhaust sensor fails – the performance of the engine and exhaust system will be adversely affected.

Catalytic Converter Failure

Playing a crucial role in the emission process of your vehicle, dangerous exhaust gases’ elements are burned off by the catalytic converter. Bigger engine issues will undoubtedly result from an improperly functioning catalytic converter.

Exhaust Leak

An engine's performance can be greatly impacted by a vehicle’s exhaust system. Back into the engine, harmful exhaust gases can flow if you have an exhaust leak. Major problems can result.

Vacuum Pressure Loss

Fuel pressure is created through a series of vacuum hoses in every vehicle. If, in any way, one of them is damaged or leaks, significant fuel pressure will be lost.

Fuel Filter Failure

If your fuel injector is clogged or dirty, a sputtering engine could result because consistent fuel flow isn't being provided.

Fuel Injectors Are Dirty

To your engine's combustion chambers, a steady flow of gas is provided courtesy of your fuel injectors. If they become clogged or dirty, a sputtering engine can result because fuel flow won't be consistent.

Spark Plug Failure

Fuel combustion is ignited by your spark plugs. The engine won't get proper combustion if one or more is failing. As it loses power, your engine will start to pop and sputter.

Check Your Gas Gauge

If you're about to run out of gas, your engine will start to sputter. This is the most common cause of all. Naturally, and very shortly, your car will not run because it will run out of gas completely. Check your fuel gauge. If your gauge isn’t reading correctly, you'll want to have it tended to by a professional.
