Induction System Cleaning
by Pat Goss
As gas prices have escalated, the crooks have come out of the woodwork with promises of huge improvements in fuel economy and all kinds of different things. Well, save your money because those miracles do not work.
Now, there are lots of things that you can do to bring your car back to what its fuel economy was when it was new. One of those is to keep the induction system clean. The induction systems are those parts that meter and direct the flow of air into the engine.
One of the major problems is that the throttle body on the induction system gets dirty. That upsets airflow and leads to decreased fuel economy. Along with that, the components past the throttle body get dirty so they need to be cleaned.
How do you go about cleaning them? Well, one thing you don’t do is you don’t go out and buy that trusty can of carburetor cleaner and start spraying it into the throttle body. You see, a lot of throttle bodies have a coating on them and if you spray the carburetor cleaner in there, it’ll damage that coating and then you’ve got real problems. You also don’t spray anything into a mass air flow sensor, doesn’t make any difference. What you are going to do, if you do that, is damage or destroy the mass air flow sensor.
So what do you do? Well, you use a kit or you have the service performed using a kit such as we have here. A chemical goes into this unit, its pressurized, it goes down through the hose, the engine is running, there’s a nozzle, just like the nozzle on a spray gun, that’s attached to the throttle body, it sprays the chemicals down into the induction system and highly specialized chemicals, like we have here, clean the throttle body and the entire induction system, including the intake valves, and it restores fuel economy.
