The map sensor is more likely the problem, since that, if it's bad, it could also set an EGR code.
Doubt that you need both.
Go for the MAP first. Re-set the computer. Take it from there.

Seems this is a known problem with car without a known cure.

Other info I have read says it's the carbon, cool down sensor, O2 sensor, EGR, MAP and on and on.

Does anyone really know what causes the stalling and hard starting?
