should i be concern? what happened was last week, a guy ask me for a jump start, but i didn't know, he didn't know how to connect the jumper cables.
he had connected them wrong, i saw smoke coming from the car and thats when i saw he didn't know what he was doing.
a day later my battery stop working and wouldn't hold any charge, whenever i jump start it.
i got a new battery and the car seems to be working fine since then, i noticed my computer was reset.
and at times i feel a little vibration coming from the engine, and now the engine sounds a little louder than it was before.
I've checked online and all the implication of what may happen to the car bothers me,
and it was after that i noticed that action with they key.
