ok I cleared all my codes and so far they haven't returned. However when I start my jag I have a high idle that dies down after five min and when I put it in gear it accelerates on its own and begins to larch up and down as if trash was in the line. Could this be from low grade fuel, fuel injectors, fuel pump, fuel filter,.......????? help im lost.

 

cant get past 200 rpm without jerking. I replaced mass airflow sensor, new throttle body new hoses new fuel rail,fuel filter could the pump be going out. Only code that returned was o2 sensor bank 2 low voltage.

 

could someone email me the file / sw to reboot my nav system.flyguychrisw@yahoo.com
