That's the Vortech for ya. Or any AFPR. Same thing happened with me, along with boiling fuel out the overflow when I deleted my charcole canister, although that was at the track.
All those issues, dozens of vacuum lines and wires, and about 10-15lbs of AFM, AFPR, O2 clamp, and Bipes all went away when I got MS. Just saying.
