What is setting “Minimum Air and TPS?
Minimum air is the adjustment of how many RPM’s the car will idle at when the Idle Air Controller is fully seated. This is important because if its to low, the car will stall, usually when coming to a stop or after being revved, and if its to high, the idle will be too high and the computer will not have proper control over the idle. Setting the TPS, if its adjustable, is also important because there is a voltage range that the computer needs to see at idle and if the minimum air was adjusted (throttle plates opened or closed) then the TPS voltage will be incorrect. You must set the minimum air first, then the TPS. To find out how to perform these, check out the tech articles.
