Sometimes when I place my car in neutral the car will idle weird bouncing between 700 and 1200 rpms sometimes higher or lower. I Tried removing the 2p connector from the IAC attached to the throttle body and it made it bounce faster but from the looks of it my IAC valve seems to be working so but I'm not sure if it could be causeing this problem or not let me know if any of you guys have had a similar problem and what you had to do.

 

Its the idle air control valve (iacv) and you need to take it completely off and spray it with carb cleaner and clean it out that should fix it!

Then after cleaning do the idle procedure to get it back to 700-750rpm when warm.

 

Alight I just pulled the iacv off completely and filled it up with carb cleaner and drained it out and spayed it out and all that good stuff saw some brown looking crap come out and then put it back on and after a few min it started idling funny again....any other ideas??
