My Turbo a few years back seems to have lost its starting fast idle mode. It used to start-up run 1400rpm. approx. briefly then return to the usual 900rpm. On warm starts it did the same, but nodays it prett-much needs a slight press on the pedal after starting to do this. What regulates this feature? My Yamaha outboard fishing boat has a similiar feature and still does it after 10 years!! Is there a relay that regulates this and where?? Gary
