misfires, rough cold idle V50

Low voltage before startup is a valid cause. Check for vacuum leaks. Has the PVC plumbing been checked? Is the coolant temperature sensor 'off', too low or high?

How were the spark plugs when you pulled them?

Check the fuel pressure at the end of the fuel rail, it should be around 42psi.

Does the starter crank a lot when cold?
