Santana Zhijun hot car has high idle speed and high fuel consumption. It is useless to replace the throttle valve and crankshaft ventilation pipe. How to fix it?

In fact, the idle speed of hot cars is normal. Simple principle. The oil in the cylinder of the car that has been parked all night sinks, and there is no oil on the crankcase and piston ring. After start-up, no-load operation. The on-board computer only supplies oil according to the usual driving conditions. Here, it is equivalent to giving a big throttle, and the speed will naturally increase. Generally, it will be normal to return to 1200 rpm after 3 minutes. A few flashes will basically keep the throttle at 1000.

Let's see what others say.
