Greg, Dan is right far as I know.
The Pcv Valve in the pass side valve cover--its hose that used to go to throttle body should go back onto PCV valve. Other open end of PCV hose gets tee's into the passive Breather hose. Breather hose connects into air duct, that's the big fat duct between air filter and TB.
Just pulling PCV hose off and capping both ends won't work. That won't let crankcase ventilate properly, pressure can build up. Not sure how ECM detects that, late model stuff has boo-koo sensors everyplace.
I can't see the breather hose from driver side valve cover in your pic. Just re-locate that breather hose, put original PCV hose back onto PCV Valve, then tee PCV hose into Breather hose.
Use whatever necessary, might need more/different hose,(fuel line or sometimes heater hose)a tee,clamps and short piece of pipe to connect the hoses. IF that cap on front of TB is where the PCV hose originally went, leave it capped. Be aware auto parts store rubber vac. caps die kinda fast, I've been recommending silicone vac. caps awhile now, look on Ebay for those.
Don't cap anything else off. All you want to do is cap off the original manifold vacuum source that used to go to PCV Valve, and connect PCV hose to the Breather side.
We call that Breather side Passive, and original manifold vac. source port/nipple/short little tube/etc. Active. Connecting PCV into Breather hose the crankcase can still breathe this way, we simply eliminate a GIANT vac. leak this way! see?
Hey it's OK to be Frustrated
This vacuum source/type hose routing stuff is simple for me 'cause I've been doing carb's and tuning for YEARS! (I also tune toilets, that's another story, LOL)
Hope this helps, Greg. Keep us posted--and some pic's of your Groove job are always appreciated, If you can.
