Noticed recently the idle is just a little higher then I remember. Usually after it's warmed up, in gear or out with AC off idle was around 7-800 RPM; with AC on it only went up a little bit, more a solid 800. Now with AC on or off it's at or just above 1000. New plugs were put in about 2 months ago, seemed to run fine initially. My issue is it just seems to vibrate too much at idle.

Is this something easily adjusted? haven't had to do this on a car since it had a carb, not sure where to start...

 

Try doing an idle relearn. Not sure if this is your problem but my max was idleing high afrer cleaned my throttle body. Have u recently cleaned yours some people clean them after they do plugs.

 

Thanks, but I gotta ask, what's an idle relearn?
