i took the iac on the plenum off as i had spoken to a few people who said u don't need it with a standard ecu. i was told it was an idle up sensor for when the air con compressor comes on ans since no air con , no need for the sensor. I WAS TRYING TO TIDY THE ENGINE BAY UP A BIT. its not that it idles slow when cold its like it doesn;t get enough fuel..... just like a cold carby motor, and u have to puLL the choke out for it to run right when cold.. it has always done it and not changed since taking the sensor off so now i'm confused.....AND ONCE ITS WARM IT RUNS FINE :(:(:(:(:(:(:(:(:(:((:((:(:(:(:(:
