My sister’s old Viva used to have this annoying problem. Whenever we stopped at a traffic light, the engine would die off if we didn’t keep revving it. So we always had to step on the pedal just to keep the car alive.

We brought it to a workshop to check, when it was there, the car is perfectly fine. It didn’t stall at all, so the mechanic couldn’t find anything wrong. We even test drove it with them sitting beside us, and still, the car ran smoothly without any issues.

But once we drove back on our own, the same problem happened again. Then we went to another workshop, and this time they managed to find the cause, it was just one wire that had come loose.
