Release time: 2020.07.04About the poor speed of the engine (jitter、Traveling car、asthma, etc.) failure，I believe you have more or less contact! Because it involves too widely，People who have been spoofed by it are not in a few。
But if you think about it carefully, the main reason for the poor idle is due toThe proportion of mixed gas is improper(that is, the air -fuel ratio is abnormal).The mixed gas is too thin/thick, which will cause unstable idle speed.
Judging:Shake caused by unstable work.
Cars:Speed Seabetspeed fluctuates up and down within a certain range.
asthma:The cold car is normal, and the hot car is intermittently jitter.
Poor performance of idle speed:
In the case of no failure of the vehicle:
Generally after cleaning the throttle，If the throttle matches or match failure，will cause the vehicle to be too high。At this time, it can be matched by manual matching (power outage and other methods) or through the diagnostic device。
In the case of a failure of the vehicle:
1. When stepping on the brake pedal，idle speed drop significantly，It means that the idle speed is too high due to the leakage of the vacuum -assisted pump。
2. When the vehicle is driving at high speed，Parking and waiting for the traffic lights to be too high，It means that the idle speed is too high due to the severe gas between the engine cylinder。
3. When the engine load is increased (turning on the air conditioner、Turn the steering wheel, etc.)，High idle speed resumes normal，Most of the air flow meter fails at this time、The front/back -end leakage of the solar terms。
b. The idle speed is too low
The main manifestations are easy to turn off during the start/shift process. The possible causes of too low idle speed are:
1. There is a blockage of the air intake system.
2. Poor idle control (such as abnormal idle switch signal abnormality、idle motor abnormalities, etc.)。
3. Injury failure (dripping or blocking、Line fault light)。
4.Egr seabet iosystem abnormalities (the valve body failure、hose leakage, etc.)。
Anti -travel leakage, belongs to circuit failure。Instead of poor line contact (related lines, etc.)，Form a certain high resistance to cause the engine to travel by car; line leakage (ignition coil leakage, etc.)，Causes engine jitter。
Yueyou shakes, it is a oil road failure。that is, when the mixed gas is thick, the car is generated，and the engine jitter when the mixed gas is thin。But to distinguish between cause
Excessive carbon deposits cause idle jitter，Specific manifestation as the difficulty of the vehicle，The engine shakes when the throttle pedal is released after starting.，Acceleration in the middle and high speed。
