Aside from new EGR valve, which was a bit over $120 just for the part, they also did a vacuum pressure test, compression test, full service on the engine, checked the master cylinder pressure, and checked every gasket for leaks. Only other “issue” found was where I unplugged the wire for the power steering pump to stop the high idle (bad sensor), but the pump itself checked out fine. I still have the intermittent ABS light, but I told them not to worry about that yet.
I was also quoted $800 for a new timing belt and water pump, but that will have to wait as well. I dumped too much money too fast into this VX and now I need to pay down some credit cards before I start again.
