my engine check light came on so i used a diagnostic tool which said mass air flow sensor defective. i replace the mass air flow sensor and the egr valve, disconnected the negative pole on the battery and when all was done i reconnected the negative pole and started the engine. .. the light did not go away, so i decided to trouble shoot... i left the engine idling and disconnected the mass airflow sensor, the engine did not stop running, i also disconnected the throttle body sensor and the same happened..here i am with both sensors disconnected and the engine running with no idea what could be the problem..
may need some help on this one
