FAQ: What Does It Mean When My Engine Sputters?


Question: Why does my engine sputter on the highway?

An engine acting sporadic, either making a sputtering sound at high speeds or suddenly losing power, leads us to suspect the fuel system first. The two most common problems with the fuel system are clogged fuel filters and failing fuel pumps (http://www.autoeducation.com/autoshop101/fuel.htm). Both issues will affect the engine and may even keep the car from starting.

Why are fuel filters so important?

Modern cars and trucks use direct fuel injection systems, while older cars rely on a carburetor. Fuel injectors and carburetors both have small openings that are easy to clog. The fuel must be clean and free of contaminants to safely deliver the fuel to the engine. That’s why fuel filters are a necessity. Most fuel filters are made from a paper-type material – easy to dispose of and replace. Some performance filters are made from a washable mesh that eliminates the need for replacement.

How do fuel pumps fail?

A broken fuel pump is usually the result of a clogged fuel filter. When the filters are clogged, the fuel pump has to work twice as hard to pump the fuel through the engine. This will cause the pump to wear out much quicker than expected.
