In 2005, the starting speed of Mazda 323 automatic car cooler was always 2500, so what happened?

The cold car starts at a high speed, and then the hot car with high speed is heated for a while, and then gradually comes down.

If the vehicle is started in the weather above 15 degrees, the idle speed of the vehicle will be around 1200 rpm after starting, so as to quickly preheat the oil and lubricate the parts.

Solution:

1. Clean the throttle valve and match it;

2, check whether there is any leakage on the exhaust pipe, the latter leakage;

3. Check the carbon deposit at the air inlet of the vehicle;

4. Check the water temperature sensor
