I had this car since 3 years ago. lately, when i start the car , regardless if its not cold, it takes about 2 tries to turn on. i scanned it and they said it was the catalyc converter (if im not spelling it wrong). i fixed that but it is still doing it. When i took it back they said it could be the emmisions, what what the hell is that? Im a girl and the only thing we know about cars is to feed them with gas (yuck) and change diapers (oli change) every three months. anyone know's what emmissions are?
