Question about 1999 Daewoo Nubira
High reving on idla speed
High idle speed on any fuel injected car engine ussually means an intake air leak or faulty idle speed motor, but maybe faulty coolant temp switch, check if coolant level in radiator is to top of neck ONLY OPEN RADITOR WHEN ENGINE IS COLD, this is for personal safety. Get a trigger spray bottle of water and spray around all parts of the inlet manifold if leak evident rgine should run slightly rough. other poss prob could be brake booster faulty or booster one way faulty or hose split. Good luck.
