Ok i am looking at buying another saturn sl2. The one i am looking to buy due to it only 500 buck with good trans and 147k miles. It run rough at idle but gets better when driving. Any ideas what the problem is? I would be awsome if i recived a fast response as i am buying the car tommorow

 

Wow! Talk about throwing a dart .........

Sneak it down to AutoZone(or similar) and run a scan on the computer

Without more info --> any comment here would be a SWAG*
