Why does a 2000 Daewoo Lanos turn off when switching from park to drive?

Answer 1

To answer your question I must put this in two parts , Firstly if the idle is low and you shift from park to drive and the engine stalls this is due to the idle being too low. When you shift from park to drive the transmission puts extra load on the engine causing it to idle lower and thus can stall. Remedy to fix is to either screw up idle adjuster but most times it's because of built up carbon in the intake throttle body causing the accelerator flap inside to not fully close . This causes the throttle positioning switch mounted on the side of the throttle body to send the wrong signal back to the computer saying that the car is not at idling position when it is. Remedy to fix this is to spray in some Carby Clean into the throttle body and then some more while the car is running, all while holding revs up on motor so it will not stall ( use the whole can ). Now the second part is that you can have a bad wiring problem with either a broken wire or bad connector . When you put the car into Drive from the park position the engine will rock ( this is on all front wheel drive vehicles ) If you have a broken wire or bad connector some where between the motor and cars wiring loom by the engine moving it can open circuit any connection that controls engine running . Remedy to fix is to put the car into park and physically move and jiggle wiring in engine bay until symptoms occurs , then it's up to you to repair the fault.
