this gives a description and I think since you have cleaned the MAP and MAF sensors I would be looking at the Throttle Body, the bit that the lower charge air hose connects to on the inlet manifold, it regulates air flow and has a air temp sensor on the side (I think it is), it may be very oily and cruddy, if the valve has restriction or not closing properly your could be getting a bit of sluggish stop and starting... worth a look anyway before heading to what i think will be the a lot of thoughts on EGR fault...
What brand of air filter and how long since replaced ???
Sensors need to be given a good flushing with sensor cleaner as well, a real good drowning and allowed to dry before refitting.
If you have a look here there's a schematic of the throttle body and parts.

Getting this checked. Cleaned the temp sensor. Removed the hose and checked inside. Looks pretty good. Cleaned with CRC throttle body cleaner.
The throttle/valve thgingy is in the open position when the engine is turned off. There is no way to see whether it closes properly (unless I start the engine while the hose is off). Probably not safe to do so?
How do I check the correct operation of the throttle?
