03 lancer interrogate.?

too much fuel is being pushed through my fuel splash and it won't stay running. running real rich. any suggestions on how to troubleshoot.


Answers:    If fuel pump be changed, run a fuel return line fund to the tank for the excess gas (in the valise of the fuel pressure regulator is restricting the higher fuel pressure from the pump)

If the pump be not changed, o2 sensor, the air intake heat sensor (usually on the throttle body but also can be on the air inlet tube)

apt luck,

Check your O2 sensors.
