i know its hear some place but i cant find it i removed the egr valve off the motor what can i do with the holes in the plenton and or the intake runners the intake is still on the motor and i dont want to take if off if i dont have to and the plentom and runners are off the motor

 

I had a friend who runs late model stockers build me a block off plate for lower intake....thats really all you need.

from my understanding, when you remove the egr, you need to reprogram the pc as there is supposed to be something in the ecm thats plays with the timing when you have egr.

 

with the mods in the car i know i will have to change the chip thanks for the input but what about the openings in the plentum should i do anything with them????? thanks

 

On the intake manifold, remove the EGR valve and put in a block off plate like LVZ2881 suggests.

Put a cap on the one air nipple on the plenum for the EGR valve vacuum hose.

There shouldn't be any other openings on the plenum for the EGR valve. There are other nipples for the FPR hose, MAP sensor, PCV, etc.
