SES Light at idle (high map sensor reading) For about a year now I have had this problem at idle only with it throwing the ses light on my 95' Trans Am. Idles fine, just really rich, once you give it gas it goes off. I checked on my scanmaster and the map reading was around 24-25 then went down when it would rev over 2,000. Its a built 383 with a decent size cam, ported and welded intake with a twin 58mm. Anyone tell me how to fix it? Or what the deal is?
