There was a post a few days ago which outlined this but I cannot find it. It is also no longer in the FAQ portion of the Tech section. Thanx in advance   Andrew Maier (Newman) Senior Member Username: Newman Post Number: 490 Registered: 04-2003 Posted on Thursday, January 08, 2004 - 11:30 pm:    Bathe it in carb cleaner. Towel dry.   Clay Mullins (Kyclay) New Member Username: Kyclay Post Number: 24 Registered: 06-2003 Posted on Saturday, January 10, 2004 - 02:14 pm:    I understand the carb cleaner and towel dry part, but I need to know the proper removal technique in order to clean it. Do you remove the bolts to release flange or does it unscrew from the flange etc?   andrew adia (Drew) Member Username: Drew Post Number: 54 Registered: 03-2003 Posted on Saturday, January 10, 2004 - 02:32 pm:    Clay, Unhook the four pin connector, then just unscrew it from the intake plenum (sp?). If your disco is a 95 or less the IAC motor is on the passanger side of the intake, if it is a 96 or newer it can be found closer to the driver side of the intake.   Clay Mullins (Kyclay) New Member Username: Kyclay Post Number: 25 Registered: 06-2003 Posted on Saturday, January 10, 2004 - 04:15 pm:    Andrew: Thanx for the info. I tried what you suggested, but the stepper will not twist out. It will only move slightly (less than 1mm)in either direction. What would you suggest next?   Corey (Discobro) Senior Member Username: Discobro Post Number: 315 Registered: 12-2002 Posted on Saturday, January 10, 2004 - 05:55 pm:    It doesn't "twist" out (96). Unbolt the two hex head screws and it should just FALL out. Be carefull when taking it out to not lose or break the little gasket that is made out of a hard fiber material. Are the screws completely removed?   andrew adia (Drew) Member Username: Drew Post Number: 57 Registered: 03-2003 Posted on Saturday, January 10, 2004 - 06:05 pm:    Clay, Yeah mine was pretty tough to get off as well. You can try to remove it when the engine is hot. Maybe the heat will expand the threads just enough to break it free. If that does not work losen it as much as possible and spray some penetrating oil or carb cleaner on the threads. Penetrating oil would most likely work better but I don't know how the stepper motor will react to it. If you do use the penetrating oil just make sure to clean off the stepper motor really well with the carb cleaner. A little persistence will get it off.
