I have aem ems and when I replaced the headgasket I also removed all my egr sensors. I also removed the fuel pressure solenoid thats on the left side of the intake manifold, Do I need this, my idle surges and I was wondering if this is causing it.

Here is a pic of the diagram

Whatever I dont need will be up for sale.

 

Emission pending. Remember you may need this if you county test. But You don't need Evap canister, EGR, Fuel pressure soleniod, EGR Vacuum soleniod, Evap emission purg soleniod, and Evap emisson vent. I think that all. Just make sure you cap off the vacuum lines comiing from the Intake manifold and throttle body
