Re: EA running rich.
The first thing that comes to mind is the oxygen sensor, however if it is not working it makes it run lean because it cant sense any oxygen. Being on a low point of the car it could have copped a hiding in the crash. If the wires that go to the oxygen sensor are shorting, I think this means it is sensing too much oxygen?? Therfore making it run rich. Im not sure but sus it out. Because it is the computer that controls mixture. Also, have a look at the two injectors, one might be leaking all the time??? Easy way to test if its a sensor causing the trouble is to plug a diagnostic tool onto the computer!!!
