Toyota-Highlander-Idle jitter problem

The causes of engine idling jitter are: serious carbon deposition, ignition system failure, unstable oil pressure and aging engine parts.

The jitter in idle state will not be reduced because of the operation of the vehicle air conditioning compressor, which is caused by the aging of the engine foot, so it is necessary to replace the engine foot in time.

The serious carbon deposition in the engine is that the throttle is too dirty or the nozzle has too much carbon deposition, which is a common cause of engine jitter. The fault of the ignition system is that the spark plug, high voltage line and ignition coil work badly after a certain period of time.

Unstable oil pressure refers to abnormal oil supply pressure of oil pump, or incorrect intake pressure sensor, which will cause engine jitter.

The aging of engine parts means that turning on the electrical system when the automobile engine is idling will increase the load of the engine and cause idling slippage.
