What Causes the Automatic Acceleration Phenomenon?

[AxelLynn]

Automatic acceleration phenomenon may occur due to the following reasons: Dirty Throttle: A severely dirty throttle with excessive carbon buildup can cause unstable idle control, sometimes leading to the engine automatically increasing its RPM. The solution is to clean the throttle. Electromagnetic Interference: Electromagnetic interference in the electronic control system can disrupt the voltage signal output from the accelerator pedal, causing unstable signals and affecting engine speed control. The solution is to repair the electronic control system and avoid sources of interference. High Engine Idle: Improper adjustment of the throttle cable or throttle position sensor can result in excessively high main oil circuit pressure and delayed gear shifting.
