Alright, I'm sure the people that follow every thread will start thinking I got a lemon, but I doubt it's the case. Since I got my car a month and a half ago, it's had problems starting. I'll turn it over, but sometimes when it sounds like it's started it just stops. And when it does turn over it doesn't always sound very healthy. Would the problem be the starter, or the original battery still being in a 2000 car, like my dad says? I'd love for it to be a simple and cheap fix. Also, not sure if this is related, but some starts result in the RPM jumping between 500 and 1000 RPM before it stops at a nice quick 950. Is this normal? Since this is my first car and my dad only knows older engines, we're kinda stuck, so any help would be appreciated.
