Yesterday I was hopping on the freeway when in 3rd gear @ 8,000rpm my car sort of cut off & made a pop noise, My car redlines @ 9 grand instaneousley the check engine light came on. I went to autozone to test the code, It read P1259 = which is Immobilizer to PCM siganl error WHAT THE FUK DOES THIS MEAN???

Also when I checked under the hood today I noticed a orange vaccum hose next to the battery against the firewall, that it's plastic top was broken, could I have sucked that peice up? Where does that vaccum line lead to???
