Resetting Your Sensors

courtesy of Bob, The Auto Answer Man

I have a 1994 Mitsubishi Diamante that I had to change the battery in. After changing it, the car did not want to idle. I contacted the dealer and they said that after the battery has been changed, you have to reprogram the computer by driving the car for about 20 minutes down the road. I did this but it didn't work. The only way I could get the car to idle was to turn on the AC which would idle up the car enough. I continued to try to reprogram the computer by disconnecting/reconnecting the battery and driving the car. Finally, it started idling. After a few months, I had a problem with the alternator and had to disconnect the battery again. This time I have not been successful to reprogram it. Is there a special 'trick' I need to do to reprogram the computer properly? Should the AC be on or off? I not sure what to try next short of taking to the dealer and paying them (which I want to avoid).

I am not sure about foreign cars, but for most US cars, you should connect the battery and then turn the key but not start for about 10 to 15 seconds. Then, once all sensors reset, start the car and just let it sit and idle for 15 to 20 minutes without touching anything. Then all should be fine.
Good Luck!
