What Causes Throttle Body Failure?
1, The car’s acceleration is significantly sluggish, and the speed drops as soon as the throttle is released;
2, the engine can not start or idle shaking, unstable work, unstable speed;
3, the instrument on the EPC light will light up, indicating that the electronic throttle control system problems.
4, engine-cooled car is not good to start, idle speed is unstable, black smoke.

When the vehicle was purchased, the first time to clean the throttle interval is certainly the longest, and after that with the crankcase ventilation and intake pipe condensation and other factors, the frequency of cleaning will become more and more intensive. Generally when driving back to the idle speed instability, oil car, acceleration break-in, etc., are generally caused by a dirty throttle.
