HONDA ASCOT ENGINE PROBLEM

1999 Honda Ascot

Engine Performance problem
1999 Honda Ascot 4 cyl Two Wheel Drive Automatic 131000 miles

My 99' honda accord's engine rpm's rev up and down at idle. I've taken it to a mechanic and they cleaned the carbon out of the manifold, I've replaced the iac motor and the map sensor and the ekg valve and it still does not stop. When I unplug the map sensor it idles correctly. I was wondering if maybe the mechanic did not put all of the vacuum lines back correctly or am I just missing something obvious.
