Not sure, did you set the base idle? Timing at 10^? Here is a Camaro forum that addresses some of your issues..http://www.thirdgen.org/techboard/v6/528213-rough-idle-never-sets.html
thank you for responding to my question. Yes I had the timing set at 10 and the idle at about 900 hundred.The problim is that is not stady.. every time I come to a stop idle goes up then I have to hit the gas pedal in order to bring it down to normal.. as soon as I put it in gear the idle goes up ans sticks, in other words regarlees of the idle and timing being set to manufacture spesifications the idle is erratic .
