My car is an 84 duke 4 speed. If i dont have a speedo gear installed in my transmission the car will never adjust idle correct? just checking. found alot of people say the idle air control will adjust automaticly once the car goes over 35, but what if the car doesnt know its going 35? thanks, i know its a dumb question.

not such a dumb question....looks like you will need to fix the VSS in order to find the answer.

ah, as i feared lol. i just need the connector and two wires if someone is willing to cut one off a parts car and sell me it ill pay shipping plus 10 bucks if that sounds fair.
