Under what circumstances does a manual transmission car stall?
2 Answers
Manual stalling can generally be divided into two categories: faults in the car itself and the driver's driving skills. There are too many issues involved in faults of the car itself, as any problem in the intake system, ignition system, or fuel system may cause stalling. Reasons for manual transmission car stalling: electrical circuit failure, possibly caused by low-voltage power interruption while driving. In this case, you can check the ignition switch, start switch, and also a fuse box. Stalling caused by a short circuit in the low-voltage line is intermittent stalling. Check the vehicle's low-voltage lines. This problem is generally related to the ignition coil, capacitor, or electronic ignition module. The car may start initially but shut off after a while, then it can be started again before shutting off; fuel system failure, damaged fuel pump, ruptured pipeline, clogged carburetor fuel inlet, or no fuel in the tank. However, in such cases, the car can be restarted, but with great difficulty. If problems occur, both the ignition system and the engine overheating explosion system will shut down.
I remember when I first drove a manual transmission, stalling was a daily occurrence. The most common situation was lifting the clutch too quickly during take-off without matching the throttle, resulting in that sudden jerk and an immediate stall. Also, when starting on a slope without using the handbrake, hitting the brakes while the car rolls back can cause a stall. Last time my friend was driving on a mountain road, he kept it in third gear climbing a hill even as the RPM dropped to 1000, and the engine just gasped and gave up. For beginners, I recommend holding the clutch at the biting point during take-off, lightly pressing the throttle to around 1500 RPM, and then slowly releasing the clutch—especially when there are passengers in the back, you'll need to give it a bit more throttle. Oh, and when slowing down, don’t shift directly from fifth to second gear; the jerking and stalling can be dangerous—downshifting one gear at a time is much safer.
