My car has not thrown out any codes to help with resolving my issue. I told the dealer to check out the fuel pump relay. When they go bad, they will cause a stall and then will restart after a short period of time. That is what my engine is doing right now. They've had my car 2 weeks now and all they have come with is a electrical wire connector at the coil pack coming lose at times. If that was the case, the engine would not restart unless you giggled the wire around, prior to restarting the engine. Am I correct or not?
