You completely waste the injector cleaner. It has to flow through the ports which supply fuel to the engine to do its job. That's why the directions tell you to put it into the gas tank in a certain ratio to gas. It mixes with the fuel in the tank, flows through the system and out of the injector ports.
Pouring the injector cleaner down the throttle body won't clean the injectors. You need to add the injector cleaner to the fuel tank for it to help you. Read the instructions on the container of injector cleaner.
No, it has a throttle body. The throttle unit resembles a carburetor except that there is no fuel bowl, float or metering jets. The fuel is sprayed directly into the throttle bore by an injector. It's actually fuel injection, except the fuel is injected in the module beneath the air cleaner as opposed to each individual cylinder.
Modern fuels have a fuel injector injector cleaner built into them. However I do recommend you use a good fuel injector cleaner such as Seafoam or Chevron Techron once a year.
Doesn't a 94 Buick have Throttle Body Injection? Try running injector cleaner through the fuel system first. As always, follow the manufacturers recomendations.
Diesel fuel injector cleaner will not hurt your unleaded gas motor. The diesel fuel injector cleaner is basically the same as your unleaded injector cleaner.
Aerosol throttle body cleaner, sprayed directly in to TB while not running. Only recently have they began labeling it TB cleaner not carb cleaner but it's the same solvent. Use copious amounts
Your Saturn has no carburetor and therefore has no gas jets. All 1993 Saturn's are Fuel Injected. The S1 is Throttle Body Fuel Injected, (TBFI). On TBFI you will see what looks like a carburetor. In fact the injector is mounted inside the top of the throttle body. Remove the air cleaner and you can see the injectors. The S2 has Sequential Electronic Fuel Injection, (SEFI). Sequential, in which injection is timed to coincide with each cylinder's intake stroke.
The IAC should be directly below the throttle body. Remove the air cleaner duct from the throttle body and air cleaner housing. You'll see a component with a 6 wire connector screwed to the bottom of the throttle body assembly.
Fuel injector cleaner does not hurt anything,but most fuels already have a cleaning additive in their fuel.
Fuel injection is cleaner and more reliable as well as easier to monitor by the onboards, there's a reason the automotive industry moved from carbs to throttle bodies then fuel injection and it's the standard now.
Chandge the fuel filter first then try running some injector cleaner through it. If that doesn't work a mechanic will have to look at it.
no i dont think you can use diesel fuel injector cleaner in gas engines
