    So the last couple days if I let my car idle for more than 20 min I have to jump it to start it. If I don't let it idle its fine. Any ideas what could be going on?

    Are you part of the under drive pulley crowd?

    And are you still running the original battery from when it was bought new? Probably going bad by now if so.

    An under-drive pulley will run your alternator at a slower than "normal" speed if you have one. Thus the possibility of it not charging fast enough when you leave it idle for a long period. 20 minutes still sounds awfully quick even for an under-drive pulley scenario. Have auto zone check your battery. Do they check alternators too? Ask them to do that too if they do.

    Oh. Duh. Lol no I don't have an under drive pulley. I'm gonna have the battery and alternator checked tomorrow.

    Have you checked for the loos battery connections. Because mostly this is the main reason for this kind of problems.. I think you should check that once. and I hope you will find the problem from there. Good Luck.
