kyleag89 Posted December 15, 2011 Posted December 15, 2011 My 89 4.0 idles really low when its cold almost to the point of stalling. Its not a vacuum issue all the lines are good, I think it might be a sensor. After it runs for a min it starts to idle normal(800rpm) but I shut it off and restart and it will take a min to get back to 800. Could an oxygen sensor cause this? The IAC is new and I cleaned the TB last night.
