My car just died yesterday and I tried over and over to start and it wouldnt. So today I double check the connections to the coil and wiggle the primary connector back and forth then the car starts but won't idle and sputters when I give the gas WTF, guess I'll just test the coil then maybe the opti to se what's up ?

 

Sounds like you need new terminals. They can be backed out of the connector and replaced. If it was an opti or the coil, it would have the problem all the time, not only when you wiggled the connector.
