I just got my car all back together a 1990 Integra GS and its idle is all over the place. Sometimes it settles down for awhile but then it drops really low. I tried adjusting the throttle cable and idle screw. When we put my intake manifold back on the egr gasket looked a little jacked/cracked. If thats sucking air could that cause it? It seems like I can smell more exhaust fumes than normal if im idling. Thanks for all of your help.
