yankeechick - keep us posted if you can on the results. Best of luck.

It's an EASY job (even I can do it), so feel free to point out the How-to from my link in a previous post above to the mechanic. It's a 30 minute MAX job. So the labour shouldn't be too much.

ps: I still recommend picking up a genuine GM part vrs the non-GM parts some of the auto parts stores carry, as the non-GM ones may not have the latest and greatest design from GM in them.

The GM part number for the Intake side P0010/11 = 12655420
and for the Exhaust side P0013/14 = 12655421

You might want to consider changing them both at the same time if $'s aren't an issue.
