I have a rough idle when I start after I leave my 88 305 overnight.
it needs to be revved 3-4 times right after I turn the key or it will sputter and die.
then the idle is choppy for the next 5 mins or so then like a switch turning on it smooths right out and runs well.

recently I started it up and then bridged my ALDL for field service mode when It was idleing rough and that cleared it right up.
I dont understand what that could have done other than bypass some sensor or computer function that is causing this problem.

could someone please Identify the problem as I am unfamiliar with computer functions in field service mode.

thanx in advance
