Got a misfire under load, the dealers scanner says cylinder 6, 8, 9 and 10. I´ve checked all plugs and replaced the coils on the left bank (6 - 10). No change regarding the misfire. I´ve searched the forums for other possibilities, and think I might have an issue with the PCV elbow, or some other vacum issue. But I do not know where this PCV elbow is. Is it under the plastic that covers the throttle body?

Anyone has a picture or drawing, or a good description of where to find it?

Thank you.

 

Here is a pic of the hose on my 04'. The 99'-03' have a different pcv hose assembly and the elbow that likes to crack.
