Why did Souranto 3.5 idle at high speed in 2006?
In 2006, the idle speed of KIA Souranto was unstable. Personally, I think it may be caused by excessive carbon deposition in the engine. I suggest checking whether the spark plug of the car needs to be replaced and whether the throttle needs to be cleaned.
There are several main reasons for high idle speed:
1, the idle switch is not turned off;
2. Idle speed control valve is faulty;
3. Air inlet pipe leaks;
4. Wrong gas distribution phase;
5. The fuel injector leaks or is blocked;
6. The exhaust system is blocked;
7.EGR valve opens at idle speed.
Solution:
1. Adjust or replace the throttle position sensor;
2. Clean or replace the idle speed control valve, and use a special decoder to basically set the idle speed;
3. Find the leakage point, seal it or replace relevant parts;
4. Check the timing mark and readjust the valve timing according to the standard;
5. Clean and check the fuel injection quantity of each injector to confirm that there is no blockage or leakage;
6. Replace the three-way catalytic converter;
7. Remove the carbon deposit on the EGR valve or replace the EGR valve.
