My battery goes dead every now and than! It will take it a week or two sometimes but other times it can be an hour? How Dow I check to see if my ground is working all the time?

What is your question?

When my Infiniti starts to miss I pull over because it’s about to die! My battery is running out of juice, so my spark is weak! I lift the hood or slam the door and it starts to run good! I think I have a bad ground from the motor to the body or somewhere else! Where do I look?

How long has your 2002 INFINITI I35 had this problem?

A year
