This is how I like to do it. You will first need to remove the large Black hose going from the intake to the throttle body. (The Intake is where your air filter is.) There will be a large clamp at each end of this hose. Remove the one close to the throttle body and also remove the small vacuum line from the hose by pulling it. Lose your clamps from your air filter cover and then you'll be able to remove the intake hose with the filter box cover to the side. This way you can dust off your air filter too, by dusting your air filter off will last a bit longer, your car will breathe better and more.
Make sure your engine is cold, then open your throttle and Soak the throttle body well with your CRC THROTTLE BODY CLEANER, then use an old toothbrush to brush against any metal surface you can reach. You'll find the brush will quickly turn black. Wipe the inside with a cloth as far as you can. Do the same thing with your throttle close. Repeat this process if you still see your throttle dirty.
Put everything back in place and then start your engine, it might take a couple of try, but pushing the gas pedal will help, if you need to. Ignore the white smoke coming out of your tailpipe, it will go away in seconds.
If you never done this before, search HOW TO CLEAN THE THROTTLE BODY in you tube, so you can have an idea how to do it.
