Wonder if it's the o2 sensors..
Actually my gas cap had the same issue,when i bought the VX & went to full up the 1rst time i realized that the cap had few missing pieces of the white ring that locks & click three times after you twist the gap.

I replaced it with a 1999 trooper gas cap at strauss auto,the nice feature about this gas cap it comes with a black button that release the vacuum pressure (sometimes not) & had ended up loosing it with a plyers,but it does do the job very well
