[QUOTE="scott degroot, post: 796861, member: 66039"] If you have a scan tool you can watch the commanded Iac percentage pid on it and on later model Fords even watch the milliamps that the Iac is requiring to move it's pintle(this is very good info to have).The Iac will open up a certain amount while you are on the gas in order to prevent the engine from just stalling if you take your foot off the gas suddenly, works on the same principle as a dashpot on a carbuerator. I think you understand what they mean buy load, it's just additional work that the engine is asked to perform, but it's a load at idle from an accessory that they are talking about here not a load from a big hill you are tyring to climb or a car you are trying to pass, becasue afterall you compensate for that load by pressing the go pedal and allowing more air to flow past the throttle plate.
