Engine Code PO430 and PO328 04 Xterra
I'm getting codes PO430 and PO328. So I need some advice from those in-the-know. A regular mechanic told me he would diagnose it (the 430) for $135 by running smoke tests of the exhaust etc. A nearby Nissan dealer charges $105 to run the thing on their Nissan computers. Am I better off with the dealer? If it's the Cat, am I better off with genuine Nissan parts or aftermarket? Am I better off with the dealer making the repairs or a regular mechanic?
Part of my problem is I'm new to the area so I'm just stabbing in the dark with mechanics, and the vehicle wasn't purchased from a local dealer. It's an 04 that runs great and has 91,000 on it. Thanks for any substantive input.
