My 2003 350Z has been to the local nissan dealer twice and they can't figure it out. Running so bad I've stopped driving it until I can find the time to take to another dealer 75 miles away. Any ideas out there?

you'll have to be just a little more specific there schmitty....what's yer z-racer doin'.
we know she's actin' up, but if we don't know what she's doin' we won't know how to treat 'er......
