Hard Start After dealer replaced cam POS Sensor and non leaking switch

[Rosco P Coltrain]

I have an early 99 7.3. After the cam position sensor and non-leaking switch was replaced on a recall. It blows black smoke and chokes and lopes for like 20 seconds on the first cold start of the day. but not again after. I took it back and they say the epb valve is out of spec and #7 glow plug is going out and it started great before. It had the glow plugs done last summer. and now they are making me pay $200 for diagonosing a problem they caused. Some advice or help would be much appreciated.

whats the non leaking switch?

It has to do with brakes and the deactivation of the cruise control. They started of fire and leaked.
