Which is the best way to clean the throttle?
It is best to remove the throttle body and clean it fully on the front and rear of the bore. Once that occurs, the computer should be able to identify the positioning of the throttle plate and adjust the idle after driving for a while.
Why does the idle go up after cleaning the throttle body?
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
Why does my computer move the throttle plate?
Depending on what the desired idle speed is the computer will move the throttle plate until the engine reaches the desired RPM. In a lot of cases, if you recently cleaned out the throttle body and this occurred right after it is because there is still debris in the throttle bore causing the plate to not move smoothly.
How to fix high idle after throttle body cleaning?
The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes. Then turn on your a/c with blower in high position for three minutes. This should fix it.
What happens when you clean the throttle plate?
Once that occurs, the computer should be able to identify the positioning of the throttle plate and adjust the idle after driving for a while. If the problem persists, then the throttle motor or throttle position sensor may have been damaged when the cleaning occurred.

Why does the throttle plate keep opening and closing?
This can happen if the throttle plate is opened and closed over and over again at a rapid pace. A computer scan tool would then need to be used to monitor the inputs of the throttle motor and the throttle position sensor to see what is going on.
Do you need to clean the throttle body?
Don’t remove the throttle body to clean it; you don’t need to. Cleaning your throttle body likely won’t do anything to solve an idle problem. It might make you feel better, but it might do little to solve an idle problem. If you have a DBW system, I would recommend leaving it alone, as you could cause more problems than you solve with a cleaning.

Can a dBW throttle plate be cleaned manually?
If you have a DBW throttle body, DO NOT MOVE THE THROTTLE PLATE MANUALLY TO CLEAN IT, especially with the key in the ON position. This will confuse the computer and it will have to be reset in order for the engine to start and run again.
Where is the throttle plate on a car?
A throttle body is located between your air intake filter and piping and your intake manifold. The throttle body acts as a valve, restricting the amount of air that can go into the engine. As you press the gas pedal, you are actually opening up the throttle plate and allowing for more air to pass into the intake manifold, and then into the engine.
