In short,

It seems that is your problem, arising from the EGR valve.

1870 = acceleration of the poor (I'm sure you already know)
0420 = Catalyst operates inefficiently (probably because of the AGR
1406 = EGR valve or related problem ....

Check vacuum hoses to the EGR ..

or take it to a shop for diagnosis reported confidence and reparations.

Hope this helps a little.
