What is the reason for the engine jitter of Buick Regal 2.0 (what is the idling jitter of Buick Regal)?
Before starting the engine every time, the vehicle should turn on the ignition key for about 3 seconds before starting the engine, so that the PP electronic throttle can learn adaptively, and the fuel system can establish oil pressure before starting the engine. This not only helps to start the engine, but also reduces the occurrence of EPC light and engine idle jitter caused by unclean throttle.
The water temperature sensor was one of the important bases for the computer to judge the working state of the engine at that time. If the engine temperature is-10℃ at the time of cold start, but the sensor "tells" the computer that the current temperature is 20℃, then the computer will inject fuel at 20℃, and the amount of oil is of course small, so it is natural for the engine to shake.
If there is carbon deposit in the valve and intake of the engine, ECU will make a wrong judgment, because carbon deposit can absorb a proper amount of fuel. For example, if the computer actually controls the supposed 100 oil and gas injection, but only 90 oil and gas actually enter the cylinder (10 oil and gas is absorbed by carbon deposits), then even if the remaining 90 oil and gas mixtures are fully burned, they cannot reach the required power, and jitter is inevitable.
