What are the reasons for ignition shaking in GAC Trumpchi GS4?
2 Answers
The main reasons for ignition shaking in Trumpchi GS4 are car tire failure, severe engine carbon buildup, and unstable oil pressure. Car tire failure: During driving, if the car tire is punctured and leaks air, or if the tire pressure is too high or too low, or if the four wheels are unbalanced, these can all cause shaking in the driver's compartment while driving. Solution: The owner should get out of the car to check the tire condition. If there is no puncture, it is advisable to perform a four-wheel alignment and dynamic balance as soon as possible. Severe engine carbon buildup: The most common cause of car shaking while driving is a dirty throttle or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in a lean mixture during cold starts, making the engine difficult to operate and causing idle shaking. Solution: Clean the engine and check the fuel system for carbon buildup, then clean if necessary. Unstable oil pressure: If the engine carbon has been cleaned, the throttle has been washed, the oil pads and spark plugs have been replaced, but the driver's compartment still shakes during driving, it is recommended to go to a 4S shop to check the fuel supply pressure and the intake pressure sensor for normal operation. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause body shaking. Solution: Check the oil pressure and replace parts if necessary.
When I first started driving the GAC Trumpchi GS4, I was quite annoyed by the ignition shake—the car body wobbled back and forth, as if the engine was protesting. There are many common causes, such as aging or worn spark plugs, which can make the engine sputter when failing to ignite. If the fuel injector is clogged, uneven fuel supply can also cause trouble. Another issue is carbon buildup in the combustion chamber, leading to unstable ignition power. Once, my car shook severely, and it turned out the ignition coil was faulty—replacing it restored smooth operation. I recommend not ignoring minor issues: use quality fuel, clean the throttle regularly, and replace spark plugs every two years to prevent problems. A smooth drive brings peace of mind, avoiding the headache of breaking down halfway.
