what the diagnosis for a 5.0 that backfires outta the intake everytime you disconnect the battery....it happens for like 3 months and then magically dissappears like nothing was wrong.....
is it vacuum or the ecu..........
once it's good it goes well until you hit bout 45 and then it starts missing for that lil time between 45 and 50 then goes away.....
