Bluebird cold car is easy to start, hot car is not easy to start, sometimes it can be started without throttle position sensor and air flow sensor?

According to what you said, I'll give you two suggestions. One is that the oil circuit of your car is obviously blocked or the idle speed controller is out of order. If so, please go to the 4S shop to check again, clean all the oil system, or replace the controller, which should be able to improve. In addition, there is another possibility that there is something wrong with your car and the high-voltage ignition wire, and the high-voltage wire must be replaced.
