I'm assuming and hoping that I just need a tune up with replacing of the spark plugs, etc. As far as I know it's been a while since they've been replaced. Anyone have any advice or other ideas? I would appreciate it.
Oh and should I completely refrain from driving the car until it's fixed? That's my big question right now, since I'm uncertain what all that means.
Thanks
