mech5107 Posted April 8, 2014 Share Posted April 8, 2014 The wax thing opens an extra air way. That's why you idle at 1600ish rpm.The coolant sensor is used to make the correction on fueling till it gets to 70 something. Also intake temp is also used to add more fuel when it is below 35ish celcious. Quote Link to post Share on other sites
