What about Santana's high idle speed?

Santana often likes to make a mistake, that is, it is not easy to idle down after running. 2。 If there is no fault code of the throttle valve, the idle valve should be tested, and if the test is good. Enter data stream 4. If the throttle is loosened by more than 5 degrees, check the throttle adjusting screw. If the throttle is less than 85 degrees, check the throttle cable clamp. 6。 Doing the first five steps won't solve the problem. See data stream group 0 10. Looking at the third data in the third and fourth items, the hot car data is above -0.6, indicating that the gas leakage in the throttle or other places is more serious. If it is above -0.8, you need to consider replacing the throttle or serious air leakage. If the idle speed cannot keep the standard idle speed above -0.8, the throttle must be replaced. Or air leakage is unacceptable. 7. After the sixth step, if the idle speed is still high, check whether the ignition time is too early. The early Santana ignition time was much earlier, and the idle speed would become higher but not lower and lower. After a novice, too long ignition time will lead to high and low idle speed.
