I know it can't be sucking outside air, I just found it interesting to add.

Yes, I removed the copper cap.

If the restriction was too small, then wouldn't the idle initially right upon start be messed up?
After the the idle messed up the first time, I took it home and popped the hood. It sat there for maybe two hours of me toggling (engine also cooling ) trying to figure out what was wrong. Eventually i got the idle back down, dont know how? Drove around again, and once again after a little bit, back to turbulence.
I geuss, i'll try drilling it a little larger but to me that doesnt make sense. Becuase it did run perfect at one point with everything on.
