so for everyone that remember my last post about my car that wasn't starting.

well the infiniti dealer said to me "there was a glitch in ur alarm, that's why it wasn't starting, it was reset and i shouldn't have that problem again"

I dont know how true that is but it starts now but it sounds different. it starts up louder now, it shakes the car a bit.

is this a good or bad thing that it sounds more powerful that before or a sign of problems?

thanks in advance
