TB vacuum line clean up

[weegee411]

On my throttle body I have 3 lines near the entry and I was wondering if I can cap all those lines off and disconnect all the electronics they run to. I don't mind a CEL because I have one anyway from my coolant temp sensor.

Those electronics are solenoids and the lines don't just run TO them they run THROUGH them in a way. So, if you disconnect them some things on the other end of the lines might stop working...

If your state doesn't require emissions, then you can get rid of them. Just make sure not to disconnect anything important, such as the fuel pressure regulator.

Yes, you can unplug the solenoids if you don't mind throwing more CEL codes.

After removal:
The WGS, FPS, EGRS and EVAPS ports don't need to be plugged. However, leave them plugged in to prevent the ECU from throwing CEL and plug the port of the evaporative canister hose on the turbo inlet hose after you remove the canister. The boost gauge may be ran off the "P"port of the throttle body or the FPS line.
