So whether this throttle should be cleaned or not, is it used?
Or if I go to wash it, how often do I wash it?
1. Dirty things are less blocked, there is no need to clean
If it is the throttle on which there is less dirt, the engine of the driving computer, it is self can adjust the intake.
It's not going to make it clogged up, and cleaning it doesn't work, it's white money.
2. Dirty things affect engine work only to wash
But when the throttle stains are more, it may be a bit blocked, it will cause this intake control is not accurate, the engine work may be affected.
Idle speed is also unstable, acceleration, power are not good, fuel consumption are high, that is because the intake of less, this time we go to wash is still very necessary.
So we do throttle cleaning, not at all to see the throttle this thing black not black, but to see if its intake is not within the permitted standard range, this is very important.
