Ive' been chasing this high idle problem for a long time. Rebuilt engine 30,000 miles ago , changed all sensors and IAC. Did'nt find any vac leaks. Checked all grounds. Pulled computer and checked connecters, no problems. Finally found the problem! Found corrosion at EEC relay at left fenderwell. Now idles at 600 rpm in drive. Latest sympton was when i tryed to pull codes reader would not connnect. Then when i turned ignition on i lost CEL untill i disconnected battery. Now everything is good. Hope this helps someone!
