Ok so when i start the car it hardly even revs past 1k and almost dies but then idles around 1200, then after driving for awhile it and i come to a red light it will drop and idle around 2k. Heres the kicker it will idle at whatever rpm i push the clutch in at or take it outta gear at under 2k. Like if i let the rpms drop down to 1k then push the clutch in it will idle around there, but if i push the clutch in at 1500 it will idle around there. So im also throwing a CEL for the IAT input high. Tonight while driving i hooked up my scanner and went through the livedata and the IAT said -40!!!. I removed the IAT sensor and it looks good and the heads still there so i cleaned it and reinstalled it but nothing. Im gonna remove the manifold tomorrow and reseal it with new gaskets and see if that helps the idle cuz im thinkin the idle is from a vac leak. I sprayed carb cleaner around it but the idle didn't change. Any other help guys?
