hello h-body friends. Im having a issue with my 78 2+2 monza 3.2 litre. when i came home the other day i realized it wasnt idleing right. i waited till morning and started it up and it took longer then usual. when it did start the idleing was 1000 rpms and it would stall out on me. i lifted the hood and found that there was a vacuum hose missing or a cap. i stuck my finger to the hole and it would suck. if i left my finger there it would run better but 8 times out of 10 when i took my finger off it would stall out again. im not sure if it needs a cap on it or a hose. i looked everywhere and didnt find a loose hose. i didnt want to cap it just in case it gives me more future problems. it is located behind my carb and a little bit lower. here are some pics so you can get a better idea what i am talking about:
these last 2 pictures are where the main hose leads to. it is the thicker one. im just moving the other ones out of the way for a better veiw. it looks to me its going streight to the top of the motor.
hopefully someone will know the exact problem i am having. thank you guys for looking this topic over and i appreciate all the help ahead of time!!
