hey man did you ever solve this? i have a 07 tl and it game the same code last night let me know what you found out .. thanks in advance

 

This could be a simple exhaust leak. How did you check for a vacumn leak if you don't mind me asking?
Could also be: primary 02,egr valve clogged or broken hose,valve clearance(rare),or a Map sensor (common)

SrA.Espi : you are in the wrong forum lol.You might want to look into Service Bulletin 08-043 .You might just need a PCM update.
