the idle surges are due to a dirt clogged idle control valve ,ICV. This has two rubber pipes attached to it and a two pin electrical connector . remove ICV and clean insides with carb cleaner . At the same time do clean the air plate and the air bore right down to the bottom end butterfly, spotlessly This will sort the idle problem .The EHA does not control idle,only the fueling mixture under various running conditions ,enrichment etc.
i hope this helps
