Just wanted to share that I cleaned my throttle assembly with carb cleaner and wd40 and immediately had problems with my idling. First, the car wouldn't start after several tries. Then, once it started, idling would not go below 1,400 rpm even after driving several miles. Turns out, i needed to disconnect my battery before doing anything with the throttle assembly. The fix is, I disconnected the battery overnight and reconnected in the morning. All good now! No need to panic or bring to the dealer. Hope this helps!

 

good info.
Hope you hang around and help again.
