I have a 1994 nissan altima named keisha. when i put her in reverse, she rattles. drop it to neutral and she stops. put it in drive she starts to rattle again just not as bad as when shes in reverse. do you have any ideas what that might be? i keep seeing everyone saying something about a gasket manifold. i also just recently got a tune up, after i got the tune up. she seemed to rattle more. ughh stupid cars sometimes i wish we still had horse & buggies 2 make everything easier. I'm thinking of dropping out of school because of these car issues i go to school in a bad neighborhood & have classes at night. so i really need some advice. THANK YOU
