How to solve the unstable idle speed or high idle speed after washing the throttle of Honda Accord?

It should be that the cleaning method is not right, which causes the cleaning agent to enter the idle motor and makes the sensor in the idle motor unstable. Driving 1000 km or so, it will be fine if the cleaning agent evaporates. I've been in this situation. The repairman said that computer matching takes time. Actually, it's all excuses Don't be fooled by them. If you want to make a claim, make a claim.
