The first cars had carburetors as a means to draw oxygen in at the proper ratio to burn with the gasoline or diesel fuel. With today’s cars, the fuel injector has proven itself to be more efficient and reliable. The downside is that although carburetors are a high-level project for an experienced do-it-yourselfer, they can be worked on by a shade tree mechanic. Fuel injectors require professional service. Working on a car in the driveway has really become a thing of the past, as modern technology has allowed cars to have much tighter design tolerances to improve efficiency and reduce pollution.
Fuel injectors typically need to be cleaned after about 30,000 miles of driving. The term “typically” refers to average vehicle use, that number can go up or down drastically based on local conditions including dust in rural areas or smog pollution during urban driving, or even based on the quality of fuel available in certain areas. Regardless, buildup and contamination is going to accrue in the fuel injector lines over time. The number one thing a driver can do to lengthen the time between fuel injector cleanings is to rigorously replace fuel and air filters ahead of schedule, but even so, the injectors will eventually get clogged.
Once the injectors begin to get clogged, a few symptoms will present themselves. At first, the RPM gauge will show sporadic readings as the injectors shoot gas through inconsistently. This will in turn cause rough idling and engine misfires. In order to compensate, the vehicle’s computer will read the engine as needing more gasoline, which won’t be used effectively causing the car to get horrible gas mileage. Eventually, as the injectors get worse, and they only get worse never better, the car simply won’t start. At that point, continued attempts to start the vehicle may or may not work, but most likely, they will just wear out the battery by running the starter motor without successfully cranking the engine.
