Honda 1989 how come the car turn off when making a turn after driven for a while

You may have a problem with the idle speed control. When the engine load increase the idle speed should be maintained at idle (often when turning many models have a pressure switch in the steering system and when pump is working harder it will let the engine know to maintain speed) If this is too much for you to diagnose while you are still learning, you can call 757-456-0722 and ask for Roy or James and request a FREE loaner car while you have us diagnose yours.
