I don't remember anyone ever actually needing an EGR valve.

Clean the freaking intakes!

Make sure the IMRC works! Both sides!

Are your cats good?
Fuel problems can cause misses too. Injectors clean? Fuel pressure good?

How do the cylinders look inside?






he just did a intake rebuild ....


i would get in there and test the egr valve, apply vacuum to the dpfe sensor and if it doesn't cause the idle to stumble then the egr valve needs to be replaced. I would also check all the connections to your headers for the egr and check the hose to and from the dpfe sensor

also if you have a hesitation or bucking off idle but the car idles great and you have good upper rpm power verify that the secondaries are not open at idle as this will cause this problem
