what are the two sensor/solenoid looking thigns on the back of the pass. side strut tower? i noticed them the other day but dont know what they go to, or if they can be deleted. if it matters i have deleted my carbon canister/ and egr. also is there anything i can do about that little group of vacuum lines that look to be a group of 4 that plug together ? half of them are plugged off, and i wanted to remove it completely if possible. thanks
