Code 8 list Limp mode for EA/CC , with possible cause as vac intake leak.
Code 2 list Limp and remedy to be Re-adapt EA..[ which you have done]
It then states if codes return, EA actuator is suspect
The problem w/actuator is there are subcodes for the offending part of actuator, but the Flash codes do not get to those... A Benz HHT scanner does.
Those address CTP and possible Resistor Pot codes.
Check everywhere for vac leak, as that jives with the limit code, and take another look at the short harness for EA actuator.

I would also put a BB in that line to the SOV that you replaced [ or unplug the SOV] for the tranny delat shift..you have a bad vac element down at the shift cable and that will go back to intake whan DS is called for [ but I do not think that is the problem]
