Daewoo Nubira Engine Problems

Daewoo Nubira idle stepper motor

Answered by CarsGuide 9 Aug 2013

The idle stepper motor would seem to be an obvious cause of the problem, but look at doing things like cleaning the throttle body and making sure there are no vacuum leaks, which can sometimes cause a high idle speed. If you want to get it checked take it to a mechanic, the problem is more likely to be mechanical than electrical.
