hi i have a 1994 with a 5.2 ram 1500 with a 5 speed transmission 4x2. every time i come to a stop my truck stalls every time. im thinking a vaccum leak ? but not sure. it only has 45k on it ( with a lot of rust lol ) . there is a check engine light and i got a code 1-2 ( battery disconnect for more then 20secs in last 50 starts ) . i cleaned the battery terminals and it did not help. wire looks good no gfs ( green fuzzy stuff ) this is driving me crazy pleas help thanks.
