car stalled out wouldnt start back up was able to jump it and drive it home i charge the battery and drove it for a week or so then it did the same thing this time i didnt recharge the battery and week away for a week in my other car when i camr home it started up no problem but i notice the vacume hose off under the air cleaner it just plugs that line so im wondering would that make it stall out and not start or is my battery no good or my altenator?
