    What is that and how do you fix it?? Is it the gas cap replacement?

    The P0125 is engine temperature not reaching the correct operating temperature. This could be cause by the thermostat being stuck open or a defective temp sensor.

Service engine soon light went on on my mitsubishi montero sport 2000

you can take it to any autozone or advanced auto to get the light scanned but before you purchase whatever sensor they tell you to get, find a good mechanic that can give a second opinion. Often a sensor can be thrown off by another faulty sensor that may not come up during scan.

I have a mitsubishi montero sport utility truck and my servic engine light came on, i noticed that it was leaking when i parked it, what do you think it can be?

As far as the engine service light, I'd go to Autozone and have them read the engine codes2_bing.gif. They'll do this for free at most autozone parts places. The codes will indicate what's wrong and you can then decide if you really need to fix it. As far as the leak, it all depends what is leaking and how quickly it leaks. Leaking a little engine or trans fluid is not a big deal. Leaking any brake fluid is always a big deal.
