Hi! I got a problem with my 2003 mitsubishi montero sport. When I make a stop or turn the engine stall. But when I am using a/c the rpm stays @ 1, so it doesn't shut oFf the engine, but sometimes didn't work. The problem started when I forgot to turned off the light, so I charged the battery. Thought something's had a problem with the battery and even changed it but never resolved the problem. Indicators like brake and check engine soon lights (amber in color) are on. If anyone could help, that is much appreciated. Thank you.
