Q: My car doesn't start up sometimes

asked by on June 17, 2016

I've had my battery checked up on and they said it's a good battery and it's at 89% but sometimes I go to start my car and it won't start. Then sometimes if I just let it sit for a few hours it'll start right up like nothing is wrong. If i get a jump it starts right away. I don't know what to do.
My car has an automatic transmission.
