I have a 1992 MGM. I took it in for emissions test saturday, and it failed. I found a vaccuum leak in the PCV line. Fixed that, and passed, but only by 1/10 of a point. High HC. After the e-check, i cleared the computer, and drove it until the check engine light came back on. The codes i got were 542, (Fuel pump circuit open), and 332, (Insufficient EGR flow). I think i can probably figure out the 332, but the 542 is kinda bothering me. The car runs fine most of the time, but sometimes it wants to stall when idling. Any help on any of these 2 issues would be appreciated.
