The typical bad idle culprit is the IAC. Idle Air Control valve/motor, even new units are bad out of the box. It is best to replace it with a quality one Napa or Dodge.

 

So when I shift into gear the valve isn't letting air get in? Or is there a mix of too much gas/air (Or a cutoff perhaps?). The combustion is failing for one reason or another. Unfortunately I'm not an experienced mechanic, otherwise I'd already know the answer hahah

Whats confusing me the most is why I'm shifting into gear and it's stalling, like if I was driving a manual trans. Park and Neutral have no resistance on the engine and it will tend not to die out on me.
