EGR/AIR Block Off plates, what do they do?
#21
I am getting a p1404 code which I am told is the egr. Will my car pass a New York state inspection (has cats) w/o the egr. If so, is there a diagram for dummies so I can block it off or remove it? Thanks.

It does have the 1404 s*&^. Where is it located please? Stupid question, I also got a p0343 cam position sensor they are two totally seperate systems I thought. Wierd that they both went off right after a tune. Except for a lil rough idle the car runs great to me.

If you're getting headers without emissions junk, there's nothing to block off - you can just pull the air plumbing out and toss it in the trash. Pull the relay for the air pump, and you can yank the pump out if you want - should be behind the turn signal lamps on the driver's side. For the EGR system, you will need one of the expanding rubber plugs to seal the hole in the top of the intake behind the throttle body, unless you already have an LS6 intake.
