99 windstar 3.8L auto
i pop the trans into neutral and coast engine on. it coasts a lot farther this way.
Question how can i get the engine to idle, it still tracks the vehicle speed even in neutral.
If i put a momentary interrupt switch in the VSS circuit do you think the engine will idle? this bugs the daylights out of me, i know it uses a lot less gas at idle. and i know it won't hurt the trans. coasting in neutral as long as i let it idle.

i believe the ECU is adding air with the Idle Air Control (IAC) which increases fuel because its MAF system.
