Stalling could be a vacuum leak(PVC?), the EGR(feeding when it should be closed), or the IAC(controls idle speed).
When you start cold, the rpms should be above 1,000 for a short while until the coolant and engine heat up a bit.
The EGR valve is on the drivers end of the intake manifole, towards the firewall, and has a vacuum diaphragm. You may be able to poke at the diaphragm and open the vavle with the engine at idle, which should cause the idle to deteriorate and possibly stall.
The IAC is on the throttle body. If sticky, it may not give the fast cold idle noted above. If so, you may be able to clean the IAC & throttle body, and correct the problem.
You may want to check fuel pressure, but if it will run at highway speeds, it should be adequate for idle rpm.

When you say pvc is that the pcv valve? Just for clarity.

Also any other maintenance done? What was whining? Like a power steering pump whine, radio hum/whine from alternator failing, maybe a tired belt or pulley?
If you replaced the pcv valve then there may be a vacuum leak like suggested. Get a bottle of $5 carb/choke cleaner and use the straw to apply it near vacuum lines, egr system, intake plenum and throttle body. If the rpm react to the spray investigate for a leak in that area.

Yes, I think PCV was what was intended. I think Autocorrect happened.
