Does computer need to be reset after putting on the idle air control for it to work properly?

The idle air control valve has to undergo a relearning process-could be 40 key cycles

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem
