LS6 with EGR

[edbird]

Got a great price on a SLP LS6 intake with EGR fitting.It was new,never installed the guy had stored and then sold the car!He also threw in a new SLP 85mm Maf!So I installed these and car runs great however,I get PO401(EGR flow insufficent)?
Any ideas?

Double check everything for a leak, especially the EGR pipe where it fits into the manifold.

I'm going to do that but it's only 32F right now so too darn cold!
Do you think it could leak though, and still idle so well and run so well?

Don't know - friend of mine got a code after doing the free EGR mod where you cut the bottom portion off and pipe wasn't sealing right at the intake. More information here: www.gearchatter.com/viewtopic8863.php

Its definitely possible, a small leak might not be noticeable.

Like the other guys said, check the EGR tube going into the manifold, make sure its fully seated, and that its secured by the screw.

Also check the other side of the EGR, where it goes into the exhaust manifold. Make sure its flush with the EGR tube and that the EGR piping doesn't have any cracks/splits in it.

If everything looks good, I would just reset the code and see if it trips again. If it does, something else is probably wrong.

OK,thanks guys!
