My smoke test

I did a smoke test on my 02' 2.7 1 small leak somewhere around Vacuum canister and a bunch coming out of my air box, I attached the smoke tube to the AOS tube just passed the TB I'am not sure why smoke came out of air box,..I did NOT remove the oil cap at the time ,So Iam guessing it pushed by the TB flapper back to the air box correct ?? Thanks Frank

PS. a new AOS and a new MAF still idles bad still get codes 1238,..Secondary fuel pump something and still misfire's on 4,5,and 6 and still A loud sucking noise when I rev it up..Thanks
