Most pre 90’s vehicles had a carburetor. Today, computer controlled fuel injection is the choice of fuel management for the best emissions, best response and drive ability. This system consists of many different sensors, a throttle body, fuel injector(s), fuel pump and a computer. Under various driving conditions and over a period of time, gasoline leaves gum, varnish and carbon on some of these components so it’s important to service and clean them regularly. A good rule of thumb is every 2 years for an average driver or about 30-40,000 km’s. This service should include cleaning the throttle body, idle air control motor and injector(s). The results are better fuel consumption, restored responsiveness and not to mention safety by curing some stalling problems. Performing this service along with a maintenance tune up would be an excellent idea.
