Stalling while Driving. Aftermarket intake issue?
When I bought this car it had a Weapon R filter on it. I would prefer the stock but it is what it is. The car started stalling when I was driving down the road. It would roll to a stop and start right back up. Sometimes I am able to take it out of gear, let it coast for a while, and then bump start it before it comes to a stop. I started poking around and found the parts in the pictures laying loose under the filter. I am not familiar with what they are or how they should be hooked up but the hose coming out of the part (I assume a valve) with the creen connector is not attached to anything. Can someone give me some insight into what that part and the round canister thing it is hooked to are used for and how they should be connected?

If the hoses connected to that solenoid valve are not blocked off ,then you have a vacuum leak . Fix that first and see if it fixes your stalling issue .
I would remove the solenoid plus the canister and just block the hose going to underneath the intake manifold .

Update: I plugged the vacuum line but that did not fix the problem. I can be driving along at 3000 RPM and all of a sudden it will quit running. If I am gong fast enough I can bump start it after letting it coast for a short distance and it will run fine for a while longer. Some times I have to roll to a stop and let it sit for a couple of minutes and then it will start right up. It acts like something is building up while running and when it stops it equalizes out and will run fine.
Any ideas? Can anyone please tell me what the vacuum valve is in the picture?

I would definitely get the stock intake on there if at all possible. Cheao aftermarket ones can cause problems like this.
That solenoid in the picture is the VFAD solenoid. The stock intake has a snorkle between the bumper and crash guard that has a shutter actuated by this solenoid. The round thing is just a vacuum canister that sits in line with the solenoid.
I would recommend getting an OBD reader and checking your short term and long term fuel trims. The random stalling could be due to anything from bad fuel pump to this intake mod. Need data to confirm.
