First teggy and my first forum post! Please help I have a 93 gsl sedan b18a1. I had a low surging idle prob so I replaced my IAC. Now my idle after warm up sits right at 1200 (beautiful idle no missfire or surgeing) i have adjusted timing down and idle screw new TPS as well calibrated perfectly to .5 at close. My question is, is this idle to high and if so what else can I do to lower idle?
