I've got a beautiful, low mileage 2003 grand prix gt. Been idling rough, starting a little rough as well and it was recommended that I change the plugs/wires. Check engine light has since turned on and I am suspecting that this will likely solve that problem as well.
After reading a few threads I am dreading this job, but it beats paying the $300 to $400 dollars places have quoted me..... I think.
