you might have put a surge in it when installing new battery did you put the neg on first???

disconnect the battery again, with it disconnected press hold the brake pedal for 30 seconds, leave the battery disconnected for 30 minutes. reconnect battery, turn key from off to on and wait 2 minutes, start the vehicle (don't touch the gas or brake for 5 minutes) this is what I did on my friends montero and it started right up and ran fine, only thing I could figure is that I caused the computer to reset and recalibrate itself, but i'm not real sure. worked for him maybe it will work for you... good luck

need radio code for 2001 Mitsubishi Montero sport. Serial number J44mT21H91P001563. I replaced the battery which reset the radio. My email: [email protected]

Brake lights or tail lights? Two different bulbs and circuit. If it's the brake lights, then check the switch located above the brake pedal.

check your brake fluid level sounds like it needs topping up

could be your alternator or a bad battery connection...

I you have fixed the problem that set the check engine light in the first place, you can disconnect the battery for 1-2 minutes and the light will go out. If you do this but haven't fixed the problem the light will remain on or will come back on shortly after you start the engine and drive. If you haven't fixed the problem, I highly recommend getting the vehicle scanned for codes and post the codes here. we can help you from there.

nope had the same problem with my 98 montero sport, change your PCV valve, cost less then 3 bucks
