All of the wastegate hoses are fine. I bought an OBD-II scanner and put it on and it says that there is a misfire.

Keep the greens DISconnected. They are a diagnostic plug that should be disconnected when the dealer gives you the car.

I would bet it's a misfire in one or more cylinders.

edit: I was right! I would guess that the combination of the intake and big turbo is not sitting well with your ECU. What other mods do you have supporting that turbo?

The greens are disconnected. They have been disconnected.

Yes, you are correct, it is a misfire in one or more cylinders.

After the problem occurred I took the turbo and intake off. So the car is back to stock in those areas. I did not put anything in with the turbo (injectors, fuel pump, etc) because I thought that the VF39 was only slightly larger and did not require them.
