CEL and low idle

[bwlknsn91]

Good luck with figuring this out. I have the same problem. Almost for a year now. Changed the EGR, IAC, Both o2's, spark plug wires, Fuel injectors, Seafoamed it, cleaned the MAF sensor. And no cracks in the duct work at all. No vacumm leak to be found and it still runs just like yours. Like crap!

Did you replace with the Canadian EGR or USDM?

I did not replace with the Canadian one. Would it still be able to pass Califronia emissions with it?

As far as I know, the Canadian version is identical except that coolant runs through it to help regulate temperature and increase life. So I would assume it would pass emissions.
