Why does your Mitsubishi Eclipse stall and idle low?

a couple of factors can affect this which include a dirty throttle body, a bad O2 sensor, a dirty air filter, bad spark plugs, wires, or the ignition coil itself, and the very last thing which would be the last thing you would replace is the fuel pump and the fuel filter but that is very unlikely but still possible, best of luck. I also own an eclipse and had there problems so just try and do the first two things on the list and if they dont work try the others.
