What causes frequent stalling during normal driving of the Changan CS75?
3 Answers
There are several reasons why the Changan CS75 may frequently stall during normal driving: 1. Circuit malfunction: This could be due to low-voltage power failure during driving, causing the engine to stall. In this case, you should primarily check the ignition and starter switches, as well as the fuse box. 2. Electrical component failure: This issue is usually related to the ignition coil, capacitor, or electronic ignition module. The vehicle may start initially but stall after a while, then restart and stall again. 3. Fuel system malfunction: Possible causes include a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or empty fuel tank. However, the car can usually be restarted in these cases, though with difficulty. 4. Sensor malfunction: Faults in sensors such as the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor can also lead to stalling issues.
As an experienced driver who often helps friends with car problems, I believe the frequent stalling of the Changan CS75 during normal driving may stem from several key component failures. First, issues with the fuel system, such as insufficient fuel pump pressure or clogged fuel lines with impurities, can cause unstable fuel supply. Second, problems with the ignition system, like worn spark plugs or damaged ignition coils, can prevent the spark from properly igniting the air-fuel mixture. Third, abnormal signals from the engine control unit (ECU) due to sensor misreporting or software bugs can cause system confusion. Fourth, an aging battery or unstable alternator voltage can lead to intermittent power supply. Any of these issues can cause sudden power loss while driving, resulting in the car stalling. Don’t underestimate stalling—it can lead to accidents on highways. It’s recommended to stop immediately, check the dashboard warning lights, and visit an authorized 4S shop as soon as possible to diagnose the trouble codes. For regular maintenance, it’s advisable to replace spark plugs and clean the fuel lines every 20,000 kilometers to prevent such issues.
As a new owner of a Changan CS75 who hasn't been driving for long, I often encounter sudden engine stalls while driving, which is quite frightening! I think this might be related to the battery. If the battery terminals are loose or aged, unstable power supply can easily cause stalling. Another possible reason is sensor malfunctions, such as a dirty or faulty mass airflow sensor or oxygen sensor, which affects the engine's precise control of fuel mixture ratio. Then there's the fuel system - a severely clogged filter can overwork the fuel pump. Stalling while driving is not only annoying but also makes steering and braking harder, which is extremely dangerous. My approach is to note down the time and road conditions after each stall to help mechanics diagnose the problem. Now I regularly inspect these components, like checking battery terminal tightness every six months to prevent minor issues from becoming major problems. When going for repairs, always choose a reliable service center - don't try to save money on this!
