ok, i still have the issue with high idle. i checked all hoses, replaced ECU, tested ICU valve, all good as far as i know.
i am thinking to check the TSP switch, is it possible if that is shot that may cause the high idle. Maybe also the AMF.
where can i find out at what rpm the auto tranny is supposed to shift gears. currently my 4th gear shifts at 50 mph/ 3k rpm, i think it has to do with my high idle or something.
