Message: <blockquote data-quote="cempaka" data-source="post: 385724" data-attributes="member: 7014">There is a wire that tells the ecu when the aircon compressor is on, this tells the ecu to raise idle to compensate for the extra load.  If it's not connected you will get the idle drop.  I had the same problem after engine overhaul when they forgot to connect back the wire.  Can talk to ah wai at bmworld about it, he will know about this.I didn't have the other problems you describe with insufficient power, crazy electrics etc so that sounds like another issue, maybe some bad grounds or too many grounding locations.  Also how many years old is your battery?</blockquote>
